Matzoh Shoppers Guide Part II

The Four Questions of Matzoh Purchasing

The First Question Is: On all other nights of the year, we do not check our matzoh and bread, although we sometimes check our flour before we bake with it; on this night of Pesach, we check our matzoh before eating it. For what are we checking?

The Second Question Is: On all other nights of the year, we eat any kind of matzoh; on this night of Pesach, some people eat only hand matzoh, others eat only machine-made matzoh, and still others eat hand matzoh for the bracha and machine matzoh afterwards. What is the basis for these different practices?

The Third Question Is: On all other nights of the year, we prepare our food leisurely; on this night of Pesach, we eat matzoh advertised as special “18-minute matzoh.” But I thought that matzoh dough becomes chometz after 18 minutes, so all matzoh left around longer than 18 minutes before baking should be chometz. So what is special about 18-minute matzoh?

The Fourth Question Is: On all other nights of the year, no guests arrive early in order to “lift up” their food before Yom Tov, but on this night of Pesach, some guests arrive before Yom Tov in order to “lift up” the matzos they intend eating at the Seder. Why do only some of my guests ask me if they can do this?

In last week’s post, we answered the first of these questions. This week we continue…

Let us now answer the second question:

“On this night of Pesach, some people eat only hand matzoh, others eat only machine-made matzoh, and still others eat hand matzoh for the bracha and machine matzoh afterwards. What is the basis for these different practices?”

Although most people today accept the use of machine matzoh for Pesach, it is instructional to understand a major dispute that existed among nineteenth-century poskim over its use. Dozens of renowned poskim and rabbonim became involved in this dispute. Unfortunately, the machlokes over the use of machine matzos became as heated as the temperature of the matzoh ovens, with each side issuing tirades.

Those who opposed the use of machine-made matzoh on Pesach did so because of the following major concerns:

  1. The economic factor: There was concern that introduction of machine matzoh would seriously affect the livelihood of many Jewish poor who were employed kneading and baking matzos.
  2. The chometz factor: There were major concerns about whether the factories’ matzoh met all the above-mentioned halachic requirements. Among the concerns raised were: Is all dough cleaned off the machinery, or does dough stick to the equipment and remain in place for more than eighteen minutes? Does the machinery work the dough constantly, or does it sit after it has begun to be worked?

Apparently, this was a big concern in the early matzoh bakeries. In a teshuvah dated Monday, Erev Rosh Chodesh Nisan 5618 (1858), the Divrei Chayim (Shu’t 1:23) refers to machine matzoh as chometz gamur (unquestionably chometz), based on the way it was produced.

  1. The lishmah factor: Another issue involved in the manufacture of machine matzos is whether it is considered lishmah? Is the intent of the person operating an electrically-powered machine considered as making matzos lishmah? The same issue affects many other halachic questions, such as the spinning of tzitzis threads by machine, the manufacture of leather for tefillin straps and batim, and the making of hide into parchment. Some poskim contend that pushing the button to start a machine is not sufficient to make it lishmah, since the pushing of the button produces only the very first action, and the rest happens on its own and, therefore, is not considered being made lishmah (Shu’t Divrei Chayim 1:23). There is much discussion and dispute about this issue in the poskim (see for example, Shu’t Chesed L’Avraham 2:Orach Chayim:3; Shu’t Maharsham 2:16; Shu’t Achiezer 3:69 at end; Sdei Chemed Vol. 7 pgs. 396-398; Chazon Ish, Orach Chayim 6:10 s.v. vinireh d’ein tzorech; Shu’t Har Tzvi, Orach Chayim #10; Mikra’ei Kodesh, Pesach II pgs. 11-17). It is primarily for this reason that many people today who use machine-made matzoh on Pesach still use hand-made matzoh for the Seder.

It is also curious to note that the initial matzoh machines over which these poskim debated were nothing more than hand-turned rollers that quickly made a large quantity of thin dough into circles, the way a cookie cutter operates. They enabled a fantastic increase in the output of one small factory.

Thirty years after the original dispute, the issue was still heated, as evidenced by the following teshuvah of Rav Yehoshua Trunk of Kutno, widely acknowledged in the latter half of the nineteenth century as the posek hador of Poland.

“On the subject of the new idea brought to knead matzos by machine, G-d forbid that one should follow this practice. Over thirty years ago, all the Gedolei Yisroel in our country prohibited it. At their head were the Av Beis Din of Tshechnov; Rav Yitzchok Meir of Gur (The Chiddushei Rim, the first Gerer Rebbe); and Rav Meir, the Rav of Kalish; all of whom signed the declaration prohibiting their use. Not a single individual was lenient about this matter. I therefore say to our brethren, ‘Do not separate yourselves from your brethren, since all the gedolim in our country prohibited this machine and virtually all the people accepted this prohibition” (Shu’t Yeshu’os Molko, Orach Chayim #43). Thus, it appears that in central Poland, where these gedolim lived, hand matzos were used almost exclusively.

Similarly, in a teshuvah penned in the year 5635 (1895), the Avnei Nezer (Orach Chayim #372), renowned posek and gadol hador a generation later, echoed this sentiment with emphasis. He writes that although he had never seen a matzoh factory, he prohibited eating this matzoh based on the fact that the previous generation’s poskim had prohibited it, quoting Rav Yehoshua of Kutno.

At about the same time that the Avnei Nezer wrote his above-quoted responsum, the Maharsham (Shu’t 2:16) was asked by the Rav of St. Louis, Missouri, Rav Zecharyah Yosef Rosenfeld, about a matzoh machine that took a half hour to prepare the matzoh. Rav Rosenfeld was highly concerned about several problems regarding this machine. The Maharsham ruled that if all the equipment is kept cool and all the other requirements are met, then the matzoh may be used.

In the contemporary world, one can plan and construct a factory for baking matzos in such a way that a minimal amount of dough adheres to equipment, and mashgichim can supervise the swift removal of any dough that sticks to the machinery. Someone who purchases machine-made matzoh is relying on the supervising agency or rabbi to guarantee that the operation runs properly.

Many rabbonim and communities contend that it is preferable to use machine matzos, because one can control the product better – thus, in German communities and in “the old yishuv” in Eretz Yisroel, machine matzos were preferred. Rav Shlomoh Zalman Auerbach,  zt”l, and his brother-in-law, Rav Sholom Shvadron, zt”l, ate only machine matzos on Pesach, as did Rav Yosef Breuer, zt”l, and I have been told of many other gedolim who ate only machine matzos on Pesach.

Among the reasons quoted for favoring machine matzos are:

1) Kneading by hand takes considerably more time before the matzoh is ready for baking. In addition, the dough is likely to warm up considerably by the hands of the kneader, which may lead to it becoming chometz.

2) Hand matzos are of uneven thickness, so that some parts of the matzoh are burnt while other parts may still be incompletely baked; thus, there could be a problem of a matzoh being removed from the oven before it is fully baked.

3) Machine matzos are thinner and thus less susceptible to leavening.

Although the following may be unappetizing, I have witnessed someone leaning over the table, busily kneading the dough for his matzoh, while beads of perspiration are falling into the dough. Aside from the lack of sanitary conditions, there are also kashrus concerns about matzoh produced this way.

On the other hand, many Chassidic circles eat only hand matzos on Pesach, following the long list of Chassidic poskim who strongly opposed machine matzos. In between these two approaches are those who feel that the kashrus of machine matzos is fine or even preferred, but who are concerned about whether matzoh produced by a machine is considered lishmah. To avoid any halachic problem, they use hand matzos at the Seder, but eat machine matzoh the rest of Yom Tov.

At this point, my son, I can answer your Third Question:

On all other nights of the year, we prepare our food leisurely; on this night of Pesach, we eat matzoh advertised as special “18-minute matzoh.” But I thought that matzoh dough becomes chometz after 18 minutes, so all matzoh left around longer than 18 minutes before baking should be chometz. So what is special about 18-minute matzoh?

Ideally, one should stop every matzoh machine every eighteen minutes to guarantee that the equipment is completely clean. However, factory owners feel that this is a non-profitable way to operate a matzoh factory. Thus, the equipment usually runs constantly with the hope that no dough sticks to it and remains from one batch to the next. To avoid this problem, many people who use machine matzoh insist on using only matzoh produced after the equipment was stopped for a thorough cleaning and examination. This matzoh is usually called “eighteen-minute matzoh,” that is, the machine has not been running for eighteen minutes from the last time that it was thoroughly cleaned.

Different hechsherim have different standards – thus, whether some dough remains on the equipment longer than eighteen minutes will depend on how tight the hechsher’s standards are. It is fair to assume that if the factory is not stopped for cleaning every eighteen minutes, some dough remains on the equipment for more than eighteen minutes from one production to the next. However, even if dough was abandoned on the equipment for over 18 minutes, it is batail, nullified, in the final product.

To quote a friend’s recent observation: “I went to a major matzoh bakery a few years ago where they had two runs simultaneously. One was mehadrin, where they stopped the equipment every 16 minutes for cleaning. The other production was constant, and we witnessed piles of dough building up along the sides of the conveyor belt that eventually mixed into the production dough.”

The Fourth Question was basically asking:

“A guest once asked me if he could pick up the matzos on Erev Pesach that he was planning on eating at the Seder. Why did he request this, and why have I never heard of this before?”

The halacha is that to fulfill the mitzvah of eating matzoh, the matzoh must be your property. Thus, one cannot fulfill the mitzvah with stolen matzoh. Some have the practice of being certain that they have paid for their matzoh before Pesach to demonstrate that the matzoh is definitely theirs (based on Mishnah Berurah 454:15).

There is an interesting dispute between poskim as to whether a guest at someone else’s Seder fulfills the mitzvah with matzoh that belongs to the host. Sfas Emes (commentary to Sukkah 35a s.v. beGemara asya) contends that one can fulfill the mitzvah of matzoh only with matzoh that one owns to the extent that one would be able to sell it. Therefore, a host must give to each of his guests their matzoh as a present before they eat or they have not fulfilled the mitzvah. However, the universally accepted practice is to follow the opinion of the Mishnah Berurah (454:15), who states that one fulfills the mitzvah with borrowed matzoh.

May we all be zocheh to eat our matzoh this year together with the Korban Pesach in Yerushalayim.

 

The Mayim Shelanu Saga

Question #1: Who owns it?

Who owns mayim shelanu?

Question #2: Occupation or Preoccupation

“May I do something else while I bake my matzohs?”

Question #3: Mayim shelanu in Montevideo

“I have some experience at baking my own matzohs, and I will be spending Pesach in Uruguay. I intend to bake my own matzohs for the Seder. Must I use mayim shelanu for baking matzohs in the southern hemisphere?”

Answer:

Among the various instructions that the Gemara provides for baking matzoh is a requirement to use mayim shelanu, which should be translated as water that rested. This article will discuss the halachic requirements that Chazal instituted.

Who bakes the matzoh?

In the time of the Gemara, matzohs were baked fresh daily, and we see that the kneading and baking was usually the responsibility of the women of the household. Until fairly recently, this was common practice in many Sefardic communities, but among Ashkenazim, matzoh production has in most places become a commercial enterprise, since at least the nineteenth century. Today, few people bake their own matzohs, although I know people in Eretz Yisroel who still do so.

What is mayim shelanu?

Let us begin by quoting the Gemara that forms the basis of our discussion:

Rabbi Yehudah said, “A woman should knead dough for matzoh only with mayim shelanu.” Rav Masneh taught this in a public lecture in Papunia, a town in Bavel where the spoken language was Aramaic. Rav Masneh quoted Rabbi Yehudah’s exact Hebrew words, mayim shelanu, which can also mean our water. The next day, all the people came to him with their buckets, requesting that Rav Masneh supply them with his water, so that they could bake their matzohs. He then explained to them that he had meant water that rested, this time using the Aramaic words, maya devisu (Pesachim 42a).

The authorities debate whether Rav Masneh was teaching this as part of the traditional Shabbos Hagadol drosha, whose primary halachic purpose is to educate people regarding the details of the laws of Pesach, or whether he was delivering this discourse on Yom Tov. If it was on Yom Tov, why would Rav Masneh have waited until Yom Tov to tell them about an essential practice necessary to bake kosher-for-Pesach matzohs? The probable answer is that Rav Masneh was a visitor in Papunia on Yom Tov and chose to discuss this topic when asked to give a guest lecture.

Why the anecdote?

The rishonim ask why the Gemara needs (or should I say kneads?) to mention the story of Rav Masneh (Yerei’im). They do not answer that it is to teach us to have a sense of humor. What was the purpose of the story? There are several interesting answers to this question, two of which we will discuss at the end of this article.

But first, let us return to the continuation of the passage of Gemara:

“Rava taught in a public lecture: a woman should not knead her dough for matzoh under the sun, nor may she use hot water, even if it was heated only by being exposed to sunlight, nor may she use water that appears to be room temperature, if it was swept out of a water heater whose coals were removed. She should be careful not to ‘raise her hands’ from the oven until she completes making the matzoh,” which is another way of saying that she should remain focused on the matzoh production until it is finished, and certainly not do anything else in the interim (Pesachim 42a).

Occupation or Preoccupation

Thus, we can now answer one of our opening questions: “May I do something else while I bake my matzohs?”

The answer is that one may not.

After the fact

The Gemara then asks what is the halacha if someone made matzoh using water that did not meet the standards mentioned above, and cites a dispute between Mar Zutra and Rav Ashi whether the matzoh may be used. Mar Zutra permitted the matzoh thus prepared, whereas Rav Ashi prohibited it. The halachic authorities rule according to Rav Ashi, that this matzoh may not be used. The authorities then debate whether this ruling applies only to the latter cases — one who kneaded the matzoh outdoors or who used warm water — or does it apply even to someone who kneaded matzoh with water that was not mayim shelanu. Rashi is quoted as having ruled that matzoh prepared with water that was not mayim shelanu is permitted bedei’evid, after the fact, whereas most authorities prohibit this matzoh.

Mayim shelanu wherefore?

Why did Chazal prohibit using water for matzoh baking, unless it rested? The poskim cite two main approaches.

According to Rashi, mayim shelanu is required because, during the winter months, the sun traverses the earth much closer to the earth than it does in the summer. Thus, the areas of the earth in which there are open bodies of water become heated to a much greater degree in the winter than they are in the summer, making the water too warm for baking matzohs. Since Pesach in the northern hemisphere is at the end of the winter, it arrives when outside water is warmer than desired for matzoh baking, until it has had ample time to cool. Since the Gemara mentions specifically that the water was lanu, many authorities maintain that the water must rest in a cool place for a minimum of twelve hours (Gra).

Mayim shelanu in the southern hemisphere

It would seem that, according to Rashi, there is no need for mayim shelanu when making matzoh before Pesach in Argentina, Australia, South Africa and anywhere else in the southern hemisphere, since, in that part of the world, Pesach falls at the end of the summer, not the end of the winter. Similarly, someone baking Pesach matzohs in the summer months in the northern hemisphere would not require mayim shelanu. Although this last piece of information may not be germane to any existing kosher lePesach matzoh bakeries, it will be of interest to those producing matzoh for the grain offerings, the menachos, to be offered in the Beis Hamikdash when it is rebuilt, speedily and in our days, since, with only two exceptions, they may not be chometz.

River water

The rishonim quote that Rashi himself held that mayim shelanu is required only when using water from a spring or a cistern, but not when using water drawn from a river. Some explain that this is because we can assume that it has already had sufficient time to cool (Responsum of Rashi, quoted by Ravyah #485, as explained by Kolbo #48). However, later authorities (Ravyah #485; Shulchan Aruch, Orach Chayim 455:1) do not accept this lenient ruling and require that river water wait several hours before use for baking matzohs.

Here comes the sun!

The second reason for mayim shelanu is that provided by Rav Eliezer of Metz, a disciple of Rabbeinu Tam and the author of Sefer Ye’rei’im, an important early halachic source. The Ye’rei’im explains that one should not use water for matzohs unless it rested, because water drawn at night from underground was heated by the sun, since the sun is on the other side of the earth at night. He rules that water drawn at the very beginning of the night can be used immediately, since it has not yet had opportunity to become hot. This lenience applies to water drawn at the very end of the day, during twilight (bein hashemashos), or at the beginning of the night.

Luck of the draw

Among the major halachic commentaries to the Tur and the Shulchan Aruch, we find three different ways of understanding the Ye’rei’im’s position:

  1. According to the Taz, the Ye’rei’im required that matzohs be baked only with water that was drawn during the evening, as described above. Any water drawn at any other time is considered to have become heated and may no longer be used for matzoh production. The Taz contends that one may not use for baking matzohs any water that was ever known to be hot, even if it was subsequently cooled and allowed to rest. Several other authorities, such as the Hagahos Semaq 222:9, and the Mizrachi, also rule this way (as understood by the Beis Yosef and the Taz.) The reason why we refer to the water as “water that rested overnight” is because usually one needs to draw it at least a day before one will use it, and prior to the night.
  2. According to the Bach’s understanding of the Ye’rei’im, one may never use water drawn at night, but water drawn in the daytime becomes usable after it has been allowed to cool until the following morning.
  3. According to the Beis Yosef’s understanding of the Ye’rei’im, water drawn any time other than twilight becomes permissible for matzoh production after it has been in a cool place overnight. Thus, water drawn at night becomes usable the morning after the following night, whereas water drawn in the daytime becomes usable the following morning.

According to all three opinions, the Ye’rei’im permitted immediate use of water that was drawn in the evening, whereas Rashi required this water to rest overnight. According to Rashi, water drawn in the daytime is acceptable for matzoh production after it has been left for twelve hours in a cool place, whereas according to the Ye’rei’im (as understood by the Beis Yosef and Bach), this water may not be used until the following morning, which is considerably more than 12 hours. The halachic authorities rule that lechatchilah one should draw mayim shelanu in the evening and then wait overnight until one uses it, which is basically following the stringencies of both Rashi and the Ye’rei’im.

This means that one draws water from a spring, well, or river immediately before twilight and leaves it in a cool place for a minimum of one complete night to allow it to cool (Shulchan Aruch Orach Chayim 455:1 and commentaries). One may draw water for several days at one time (Shulchan Aruch 455:1), provided one draws the water immediately before twilight and then stores it in a cool place, although some poskim prefer that the water be drawn freshly each night (Maharil quoted by Ba’er Heiteiv 455:7). The water should not be drawn or stored in a metal vessel since metal conducts heat and warms the water (Magen Avraham 455:9). In addition, the water should not be drawn or stored in a vessel that has been used previously to hold other liquids since some liquid may mix with the water, and this may cause the dough to rise faster than otherwise (Magen Avraham ibid.). Many contemporary poskim discourage using tap water for matzos because of concern that fluoride and other chemicals introduced into the water may cause the dough to rise more quickly (see Mo’adim U’zemanim 3:261). It is important to note that the requirement for mayim shelanu is not only for the matzos eaten at the Seder, but also for all matzos eaten during the entire Pesach.

Rav Masneh’s lecture

At this point, let us return to a previous question: The Gemara tells us the amusing anecdote concerning the misunderstanding that resulted from Rav Masneh’s lecture, where the people misunderstood mayim shelanu to mean Rav Masneh’s water, until he clarified that it meant water that rested overnight.  Why is it important for the Gemara to tell us this story? From the Ye’rei’im onward, many halachic authorities discuss this question, providing a variety of answers. Some explain that Rav Masneh delivered this lecture on Yom Tov, and they infer the following conclusion: If matzoh made without mayim shelanu is prohibited, Rav Masneh would have left the people of Papunia with nothing to eat – they would have had to destroy all the matzoh they had already produced, since it was not made using mayim shelanu, and they would have had nothing to eat the next day either, since they had no water with which to bake. Since the Gemara mentions nothing of the hardship that was imposed by his ruling, we should conclude that the Gemara’s purpose is to teach that mayim shelanu is required only lechatchilah, but, after the fact, matzoh made using water that was not mayim shelanu is permitted (Sefer Ye’rei’im).

Others contend that Rav Masneh taught this as part of the Shabbos Hagadol drosha, and that Pesach that year began on Sunday night. (In our current calendar implemented by Hillel Hanasi, Pesach cannot begin on Sunday night. However, Rav Masneh lived at a time when the central Beis Din still determined the calendar on a monthly basis, and, in that era, Pesach could begin on any day of the week.) On Sunday, the people came to fetch water from Rav Masneh, intending to bake their matzohs in the afternoon. This was the common practice in earlier days – matzohs for the Seder were not baked until the afternoon of Erev Pesach, a practice mentioned in Shulchan Aruch and still practiced by many.

Now that they had no water with which to bake their matzohs, what were they to do for matzohs for the Seder? Since the Gemara does not say that they had a matzoh-less Seder, there are a few options:

  1. As we mentioned above, it could be that mayim shelanu is only a lechatchilah rule, but, after the fact, one who has no mayim shelanu can bake matzohs with room temperature water (Raavyah; Semag).
  2. As long as several hours have elapsed since the water was drawn, it is called mayim shelanu, regardless as to when it was drawn. Thus, having heard Rav Masneh’s ruling, the people immediately drew water and began timing the cooling off period. Towards evening, they baked their matzohs (Ravyah #485), or possibly even in the middle of the Seder!

As we all know, matzoh is made of only two ingredients, kosher-for-Pesach flour and water. Although few of us bake our own matzohs, we now know that there are halachos germane to what water one must use for baking matzohs. This provides some information that enables us to understand what is involved in the kashrus of one of the two ingredients in the manufacture of matzoh.

Baking with Hallel!

While baking matzoh on erev Pesach, there is a custom of singing Hallel with tremendous emotion. The moments that we recite Hallel then, and on Pesach itself, can encapsulate the most fervent experience of His closeness. Reliving Hashem’s miracles rekindles the cognizance of Hashem’s presence. In the merit of joyously performing the mitzvos of Seder night, may we soon see the return of the Divine Presence to Yerushalayim and the rededication of the Beis HaMikdash, and be zocheh to fulfill all of these mitzvos, including the korban Pesach!

 

 

Practical Aspects of Matzoh Baking

Question:

Personally, I find the different terms used in reference to matzoh very confusing: On the one hand, I have been told that if one is working on the dough constantly, one need not be concerned if more than eighteen minutes elapses before the matzoh is baked. On the other hand, I have been told that if eighteen minutes elapses, the dough becomes chometz. And then I see a product advertised as “Eighteen minute matzoh.” I thought that if it is more than eighteen-minute matzoh, it is chometz. Also, could you explain to me the advantages of hand matzoh over machine matzoh, and if there is a valid reason why some people use only shmura hand matzoh for the entire Pesach.

Answer:

In order to answer your question, it is necessary to explain the process of making matzoh. Although matzoh is the simplest of products, just flour and water, a tremendous amount of detail is involved in preparing it in a halachically correct way. We will divide our discussion into three headings: the flour, the water, and the manufacture.

The flour requirements

To fulfill the mitzvah of eating matzoh on seder night, one must be certain that the flour was “guarded” to guarantee that it did not become chometz.

It is important to clarify that there are two different halachic issues. The first factor is that one must be careful that the matzoh is baked in a way that it does not become chometz, so that one does not, G-d forbid, violate the prohibition of eating chometz on Pesach. This concern exists for all matzoh that one may consume any time during Pesach.

However, even if one is guaranteed that the matzoh is 100% free of any concerns that it has become chometz, there is an additional requirement so that the matzoh eaten at the seder fulfills the mitzvah of eating matzoh. This matzoh must be made lishmah – meaning, that one must supervise the process and be sure that the matzoh not become chometz, specifically for the sake of fulfilling the mitzvah.

The concept of lishmah

There are several mitzvos that can be performed only with an item that is made lishmah: this means that it is manufactured with the specific intention to be used for the mitzvah. These include the mitzvos of tzitzis, tefilin, mezuzah, and matzoh. Thus, for example, the leather used in the manufacture of tefilin must be tanned specifically for the kedusha of the mitzvah of wearing tefilin. For this reason, when placing the hide into the chemical solution that makes the hide into usable parchment or leather, one must state that it is being manufactured lishmah. Even a small job such as blackening the tefilin straps should be performed specifically for the sake of the mitzvah of tefilin. For this reason, prior to repainting one’s tefillin, one should state that he is doing this for the sake of the mitzvah of tefilin.

In a similar way, the manufacture of matzoh is required to be lishmah. For this reason, before beginning work in a matzoh bakery, the workers say: Kol mah she’ani oseh hayom hareini oseh lesheim matzos mitzvah, “Everything that I am doing today, I am doing for the sake of producing matzohs that will be used for the mitzvah.”

Although the Gemara (Pesachim 40a) discusses the fact that the flour used for the mitzvah of matzoh must be prepared lesheim matzos mitzvah, it does not state clearly at what stage this is necessary. Among the early poskim, there are three opinions as to the stage from which one is required to guard the flour from becoming chometz and from which one must prepare the flour lesheim matzos mitzvah: from the time of harvesting, from the time of grinding, or from the time of kneading. Shulchan Aruch rules that it is preferable to “guard” the wheat from the time of the harvest, but it is satisfactory to use wheat that was guarded only from the time of grinding. Other poskim require lishmah from the time of the harvest. In normal usage, “shmura matzoh” refers to matzoh guarded from the time of the harvest.

Harvesting lishmah

There is a dispute among Rishonim whether any act that must be performed lishmah can be performed only by a Jew, or whether it can be performed by a non-Jew who is instructed by a Jew standing over him to perform this act lishmah. This dispute has major ramifications for many mitzvos, such as preparing hides to be made into parchment for writing tefilin, mezuzos and sifrei torah, and preparing hides for manufacture into tefilin “batim” and tefilin straps, or preparing threads for manufacture into tzitzis. According to the first opinion, hide that was tanned by a non-Jew for the sake of the mitzvah is not kosher for use. According to the second opinion, if a Jew stands and instructs the non-Jew to tan the hide lishmah and remains near him, the resulting hide or parchment can be used for the mitzvah.

Based on the above dispute, some contend that a Jew should operate the controls that cause a combine to harvest the wheat to be used for shmurah matzoh.

At times, it seems that matters were simpler when wheat was harvested by hand. A friend of mine, who was born in the Communist Soviet Union, described to me how his father harvested wheat for matzoh baking with a hand-held sickle. However, even harvesting the wheat by hand under these circumstances creates its own interesting shaylah. Poskim rule that when cutting grain for matzoh in a non-Jew’s field, one should preferably not cut the grain that he himself intends to use for mitzvas matzoh (see Sdei Chemed vol. 7 pg. 377). This is because of concern that the field might have been originally stolen, and thus the matzoh baked with wheat from this field might be considered stolen matzoh, which is invalid for matzos mitzvah. There is a complicated halachic reason why this concern does not exist when harvesting wheat for someone else to use.

The water requirements: Mayim shelanu, water that remained overnight

The Gemara states that all matzoh used on Pesach must be baked exclusively with water that remained overnight, called mayim shelanu (Pesachim 42a). One should draw this water from a spring, well, or river during twilight (or immediately before) and leave it in a cool place for a minimum of one complete night to allow it to cool down (Shulchan Aruch 455:1 and commentaries). Maharil contends that it is preferred to draw the water the day before the baking, rather than draw water several days in advance (quoted by Be’er Heiteiv 455:7). The water should not be drawn or stored in a metal vessel, since metal conducts heat and thus causes the water to become warm (Magen Avraham 455:9). In addition, the water should not be drawn or stored in a vessel that has been used previously to hold other liquids (Magen Avraham ibid.). The latter vessel is not to be used out of concern that some liquid may mix with the water, and this may cause the dough to rise faster than it would otherwise. Many contemporary poskim frown on the use of tap water for matzoh baking out of of concern that the fluoride and other chemicals introduced into the water may cause the dough to rise faster (see Piskei Tshuvos 455:7).

It goes without saying that one may not use warm water for making matzohs, nor may one work in a warm area (Pesachim 42a; Shulchan Aruch 455:2). It is important to note that the requirement for mayim shelanu is not only for the matzohs eaten at the seder; all matzohs eaten the entire Pesach must be baked exclusively with mayim shelanu.

The manufacture of the matzoh

There are many halachos implemented by Chazal to guarantee that the dough does not become chometz prematurely. For example, one must wait a day or two from when the wheat is ground until it is mixed with the water (Shulchan Aruch 453:9). This is because of concern that the flour may still be warm from the friction of the grinding, and will therefore leaven too quickly. One may not knead the matzoh dough in a place exposed to the sun or in a warm area. One must be very careful that the heat from the matzoh oven does not spread to the area where the dough is kneaded or where the dough remains until it is ready to be placed inside the oven (Shulchan Aruch 459). Thus, a matzoh factory must be set up in a way that the kneading area is close enough to the oven to allow for speedy baking of the matzoh and yet be positioned in a way that the kneading area is not heated up by the oven.

Eighteen minutes

Our original question was: I have been told that, technically speaking, if one is working on the dough constantly, one need be concerned if more than eighteen minutes elapses before it goes into the oven. On the other hand, I have also been told that one may not pause once one begins to work the dough out of concern that the dough will become chometz immediately. And I have also been told that the Gemara and Shulchan Aruch state that one cannot wait more than eighteen minutes after the water is added to the flour. Which of these statements is correct?

We now have enough background information to address this question.

As strange as this answer may seem, all the above statements are correct, as we will explain. Shulchan Aruch rules that one should not leave the dough for even a moment without working it, and that if one leaves dough for eighteen minutes without working on it, the dough becomes chometz. Furthermore, Shulchan Aruch states that once the dough has become warm from working with it, it will become chometz immediately if it is left without being worked (Orach Chayim 459:2). This implies that once the dough is warm from the kneading, it becomes chometz immediately if one stops working on it. Although there are more lenient opinions regarding whether the dough becomes chometz immediately, all opinions are in agreement that one must not allow any unnecessary waiting without working on the dough (see Mishnah Berurah 459:18; Biyur Halacha ad loc.; Chazon Ish, Orach Chayim 121:16). Thus, in practical halacha, it is really a much bigger concern that the dough is kneaded constantly than whether it actually took eighteen minutes from start to finish.

Machine Matzoh

Although the use of machine matzoh for Pesach has now become almost universally accepted, it is educational to understand the dispute that existed among nineteenth-century poskim concerning eating machine-made matzohs for Pesach. When the first factories began producing machine made matzoh for Pesach use, many great poskim, including Rav Yosef Shaul Natanson, author of the multi-volume work Shaylos u’Teshuvos Sho’el u’Meishiv, were vehemently opposed to their use on Pesach. Their opposition centered primarily over the following three major issues:

1. The economic factor: There was a major concern that the introduction of the machine matzoh would seriously affect many Jewish poor, who were gainfully employed in kneading and baking matzohs. Although the problem of Jewish poor is unfortunately still with us, it is doubtful that the increased use of hand matzohs would have significant impact on their plight.

2. The chometz factor: There were major concerns whether the factories were producing matzoh that met all the above-mentioned halachic requirements. Among the concerns raised were: Is the machinery thoroughly cleaned after each run, or does there remain dough in place, stuck to it for more than eighteen minutes? Is the dough being worked constantly, or is it left to sit after it has begun to be worked?

In the contemporary world, a factory for baking matzohs can be planned and constructed in a way that a very minimal amount of dough adheres to equipment, and mashgichim can supervise that whatever dough remains can be removed swiftly. One who purchases machine-made matzoh is relying on the supervising agency or rabbi to guarantee that the operation is run in a proper fashion.

3. The lishmah factor: There is another issue involved in the manufacture of machine matzohs – Is it considered lishmah? Is the intent of the person operating an electrically-powered machine for the sake of manufacturing matzoh considered making matzohs lishmah? The same issue affects many other halachic questions, such as the spinning of tzitzis threads by machine, and the manufacture of leather for tefilin straps and batim (or parchment). There is much discussion and dispute about this issue raised in the poskim, and it is still disputed by contemporary poskim. (See Sdei Chemed, Vol. 7, pgs. 396-398; Shu”t Maharsham 2:16; Chazon Ish, Orach Chayim 6:10 s.v. vinireh d’ein tzorech; Mikra’ei Kodesh, Pesach II pgs. 11-17.) It is primarily for this reason that most halachically-concerned people today who use machine-made matzoh on Pesach still use hand-made matzoh for the seder.

Problems that emerge during the baking:

There are two very common problems that can occur while the matzoh is being baked: A matzoh that is kefula (folded) and one that is nefucha (swollen). A matzoh kefula is a matzoh folded in such a way that the area between the folds is not exposed directly to the flame or heat of the oven. This area between the folds does not bake properly, and thus, that section of the matzoh becomes chometz-dik and must be discarded (Rema 461:5). A matzoh nefucha is a matzoh that swells up, usually because it was not perforated properly (Rema 461:5 and Taz). Thus, while baking, air is trapped inside the matzoh. The matzoh looks as if it has a large bubble in it. If the swollen area is the size of a hazelnut, the matzoh should not be used (Mishnah Berurah ad loc. #34).

To avoid discovering these problems on Yom Tov, it is a good idea to check one’s matzohs before Yom Tov to be certain that none of the matzohs are kefula or nefucha. I can personally attest to having found both among the matzohs that I had intended to use for the seder. One should also verify that the bakery separated challah from the matzohs, or else be certain to separate challah before Yom Tov.

Is there an advantage in eating only shmura matzoh the entire Pesach?

There are poskim who recommend eating only shmura matzoh the entire Yom Tov. There are two reasons cited for this practice. Some are concerned that when the grain ripens, it can become chometz even while still on the stalk. By eating no matzoh other than shmura, one guarantees that this problem not occur, since shmura wheat is harvested before it is fully ripe (Biur Halacha to 453:4 s.v. Tov). A second reason for the practice of eating only shmura is to fulfill the mitzvah of eating matzoh the entire Pesach. Although there is no requirement to eat matzoh except for the seder night, one fulfills a mitzvah each time one eats matzoh during Pesach (see Baal HaMaor, end of Pesachim). Some contend that one should strive to fulfill this mitzvah with matzoh that is made lishmah from the time of harvesting. According to both approaches, this practice is a chumra only and not halachically required.

Your very own Matzoh

The halachah is that one can fulfill the mitzvah of matzoh only by eating matzoh that is your property. Thus, one cannot fulfill the mitzvah with stolen matzah. Some have the practice of being certain that they have paid for their matzoh before Pesach, in order to demonstrate that the matzoh is definitely theirs (based on Mishnah Berurah 454:15).

There is an interesting dispute between poskim whether a guest at someone else’s seder fulfills the mitzvah with matzoh that is the property of the host. Sfas Emes (commentary to Sukkah 35a s.v. bigemara asya) contends that one does not fulfill the mitzvah, unless one owns the matzoh enough that one would be able to sell it. Since a guest cannot sell the matzoh that the host is serving, Sfas Emes contends that a host must give each of his guests their matzoh as a present before they fulfill the mitzvah. However, the universally accepted practice is to follow the opinion of the Mishnah Berurah (454:15), who states that one fulfills the mitzvah with borrowed matzoh.

We should all be zocheh to eat our matzoh this year together with Korban Pesach in Yerushalayim.
