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 matzoh that takes more than eighteen minutes 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.
In order to answer all these questions, I must first 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 chometz, there is an additional factor required for the matzoh that is used at the seder: This matzoh must be made lishmah – with the specific intention of making it 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. These include the mitzvos of tzitzis, tefillin, mezuzah, and matzoh. Thus, for example, the leather used in the manufacture of tefillin must be tanned specifically for the mitzvah of wearing tefillin. For this reason, when placing the hide into the chemical solution that makes the hide usable as parchment or leather, one must state that it is being manufactured lishmah. Even a small job such as blackening the tefillin straps must be performed specifically for the sake of the mitzvah of tefillin. Thus, one who repaints his tefillin must recite before painting them that he is doing this for the sake of the mitzvah of tefillin.
In a similar way, matzoh for the seder must be lishmah, meaning that it is manufactured with specific intention that it not become chometz so that it can be used to fulfill the mitzvah of eating matzoh on seder night. For this reason, before beginning work in a matzoh bakery the workers say: Kol mah she’ani oseh hayom har’eini oseh lesheim matzos mitzvah, “Everything that I am doing today, I am doing for the sake of producing matzos that will be used for the mitzvah.”
In addition, the preparation of the flour and the drawing of the water must be performed for the purpose of fulfilling the mitzvah of eating matzoh. This intention is referred to as preparing the flour and water lesheim matzos mitzvah.
Although the Gemara (Pesachim 40a) discusses that the flour used for the mitzvah of matzoh must be prepared lesheim matzos mitzvah, it is unclear from the Gemara at what stage the flour must be guarded from chimutz for the sake of matzos mitzvah. Among the early poskim, there are three opinions:
(1) From the time of harvesting
(2) From the time of grinding
(3) From the time of kneading
The Shulchan Aruch rules that it is preferable to guard the wheat from the time of the harvesting, 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 common usage, “shmura matzoh” refers to matzoh that was guarded from the time of the harvest.
There is a dispute among rishonim whether an 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 tefillin, mezuzos and sifrei torah, and preparing hides for manufacture into tefillin “batim” and tefillin 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 near the non-Jew and instructs him to tan the hide lishmah, the resulting hide or parchment can be used for the mitzvah.
Similarly, there is a dispute whether a non-Jew may operate the combine used to harvest the shmura wheat, or must a Jew operate the controls that cause the combine to harvest the wheat. (According to some opinions, it is insufficient to have the Jew operate the controls of a regular combine, since the harvester, once it is turned on, continues to operate automatically. Thus, this is considered that the Jew harvested the wheat indirectly. Instead, the combine must be set up in a way that it cuts grain only when the stick is held in a specific position. Thus, the Jew is actually doing the harvesting himself by using the combine as his sickle!)
At times, it seems that matters were simpler when wheat was harvested by hand. A friend of mine, who was born in the Soviet Union, described for 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 (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, Orach Chayim 455:1 and commentaries). Maharil contends that it is preferred to draw the water the day before the baking, rather than draw water for several days in advance (quoted by Be’er Heiteiv, Orach Chayim 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 because of concern that the fluorine 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 matzos, nor may one work in a warm area (Pesachim 42a; Shulchan Aruch, Orach Chayim 455:2). It is important to note that the requirement for mayim shelanu is not only for the matzos eaten at the seder, but that all matzos 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 prematurely become chometz. For example, one must wait a day or two from when the wheat is ground until it is mixed with water (Shulchan Aruch, Orach Chayim 453:9). This is because of concern that the flour is still 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, Orach Chayim 459). Thus, a matzoh factory must be set up such that the kneading area is close enough to the oven to bake the matzoh quickly, yet be far enough away that it is not heated up by the oven.
Our original question was: I have been told that if one is working on the dough constantly, it is not a concern if more than eighteen minutes elapses before the dough 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 it 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. Shulchan Aruch rules that one should not leave the dough for even a moment without working it, and that dough left for eighteen minutes without working it becomes chometz. Furthermore, Shulchan Aruch states that dough that became warm from kneading will become chometz immediately if it is left without being worked on (Orach Chayim 459:2). Although there are more lenient opinions as to whether the dough becomes chometz immediately, all opinions agree that one must not allow any unnecessary waiting without working on the dough (see Mishnah Berurah 459:18; Biur Halacha ad loc.; Chazon Ish, Orach Chayim 121:16). Thus, it is a much bigger concern that the dough is worked with constantly, than whether it actually took eighteen minutes from start to finish.
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 over their use for Pesach. When the first factories began producing machine-made matzoh for Pesach use, many great poskim were vehemently opposed to using it on Pesach. Their opposition centered primarily over the following three 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 by kneading and baking matzos. Although the problem of Jewish poor is unfortunately still with us, it is doubtful that the increased use of hand matzos would have significant impact on their plight.
2. The chometz factor: There were major concerns whether the factories were producing matzoh that met all halachic requirements. Among the concerns: Does all the dough get cleaned off the machinery, or is some dough stuck to the machinery that remains in place 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 matzos can be planned and constructed in a way that a very minimal amount of dough adheres to the equipment, and mashgichim can supervise that whatever dough is stuck 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 matzos – is this process considered lishmah? Does the intent of the person operating an electrically-powered machine and his supervising the production make the matzos lishmah? The same issue affects many other halachic questions, such as the spinning of tzitzis threads by machine, and the manufacture of leather for tefillin 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 authorities. (See Sdei Chemed Vol. 7 pgs. 396-398; Shu”t Maharsham 2:16; Chazon Ish, Orach Chayim 6:10 s.v. Venireh de’ein tzorech; Mikra’ei Kodesh, Pesach II pgs. 11-17.) It is primarily for this reason that many 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 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 the entire matzoh becomes chometz-dik and must be discarded (Rema, Orach Chayim 461:5). A matzoh nefucha is a matzoh that swells up, usually because it was not perforated properly (Rema, Orach Chayim 461:5 and Taz). Thus, while baking, air is trapped inside the matzoh. The matzoh looks like 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 matzos before Yom Tov to be certain that none of the matzos are kefula or nefucha. I can personally attest to having found both among the matzos that I had intended to use for the Seder. One should also verify that the bakery separated challah from the matzos, or else be certain to separate challah before Yom Tov. Under these circumstances, it is not permitted to separate challah on Yom Tov or Shabbos.
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 once the grain ripens, it can become chometz even while still on the stalk. By eating only shmura matzoh, one avoids this concern 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 in order to fulfill the mitzvah of eating matzoh the entire Pesach. Although there is no requirement to eat matzoh after the seder night, one fulfills a mitzvah by eating matzoh the rest of Pesach (see Baal Hamaor, end of Pesachim). 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 only a chumra and not halachically required.
The halacha 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 matzoh. 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 whethera guest at someone else’s seder fulfills the mitzvah with matzoh that is the property of the host. Sfas Emes (Sukkah 35a, s.v. Bigemara asya) contends that fulfilling the mitzvah requires that one owns the matzoh that he is eating — enough that he could sell it. Therefore, a host must give to each of his guests their matzoh as a present 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.
We should all be zocheh to eat our matzoh this year together with Korban Pesach in Yerushalayim.
