This is the Way We Bake Our Bread! – Some Practical Questions about Hilchos Challah

clip_image002Shaylah #1: Mrs. Ginsburg calls me with the following question:

“I like to separate challah with a bracha, but I do not have a bowl big enough to hold the minimum amount of dough necessary. Instead, I have been mixing the dough in two bowls, and draping a cloth over them. Someone told me that this is not a satisfactory method of combining the doughs and that I have been reciting invalid brachos as a result. What is the correct way to separate challah?”

Shaylah #2: Mrs. Bracha, Mrs. Ginsburg’s friend, was curious why Mrs. Ginsburg was trying to combine her two doughs. “After all, let her just ‘take challah’ on each bowl separately. Why all this hassle?” Which of the two good ladies is correct?

Shaylah #3: In preparation for Shalach Manos, Mrs. Lowenstein is baking her challahs in small batches and placing them in her freezer. Should she separate challah from them?


In the last question, I used the word challah to mean two completely different things – our special Shabbos bread, and the consecrated portion that we separate from dough. Indeed a very strange misnomer has occurred in both Yiddish and English that often creates confusion. Whenever someone mixes a large dough or batter intending to bake it, he or she is required to separate a special portion called challah. In the time of the Beis HaMikdash, a generous portion was separated from each dough and given to a kohen. Only a kohen or his family and only when they were tahor could eat the challah, which had special sanctity. Today, since we are all tamei and cannot rid ourselves of this tumah, no one may eat the challah; therefore we separate a small piece, which we burn or dispose of respectfully.

On the other hand, the word challah also came to refer to our special Shabbos bread . To avoid confusion, I will refer to the special Shabbos bread as “bread,” rather than challah, and the word “challah” will refer to the consecrated portion separated from dough or bread to fulfill the mitzvah.

Indeed, it is a very important mitzvah for a woman to bake bread for Shabbos, rather than purchase it from a bakery (Bi’ur Halacha, Orach Chayim 242 s.v. vehu), and it is an even bigger mitzvah to bake enough to separate challah with a bracha (Rama, Orach Chayim 242). However, as we will see in discussing the questions raised above, these mitzvos can sometimes become complicated.

The Torah teaches us the mitzvah of challah in Parshas Shlach (Bamidbar 15:18-21). I quote some of the pasukim:

(18) Speak to the children of Israel and say to them, upon your entry to the land that I am bringing you there.

(19) And it will be when you eat from the bread of the land, that you should consecrate a special portion for Hashem’s sake.

(20) The first of your kneading bowls is challah; you should consecrate it just as you consecrate part of your grain.

Note that Pasuk 19 refers to separating challah when you eat bread, whereas Pasuk 20 mentions taking challah from your kneading bowls. This leads us to a question: Why does the Torah tell us to separate challah from bread if we already separated challah when we were kneading it? The two references imply that sometimes we must separate challah when kneading dough, whereas at other times we are not obligated to do so until it is already bread. Stay tuned to find out how this applies.


Before answering Mrs. Ginsburg’s question, we need to explain the basic method of challah taking.

The simplest method of separating challah is as follows:

1. Separate a piece of the dough that will become the challah portion, but do not intend that it should become challah yet. The custom is that the piece should be at least as large as a small olive (Rama, Yoreh Deah 322:5).

2. Touch the piece to the rest of the dough.

3. Recite the bracha Asher kidishanu bimitzvosav vitzivanu lihafrish challah. Many people have the custom of adding the words min ha’isah to the end of the bracha. (Others end the bracha with the words lihafrish terumah, lihafrish terumah challah, or lihafrish terumas challah instead of lihafrish challah.)

4. Declare that the piece is challah. If saying this part in Hebrew, simply say “Harei zu challah.” One can just as easily say in English: “This is Challah.” Technically, one does not need to declare the portion challah verbally; it is sufficient to simply think which piece becomes challah. (This last case is useful when someone serves you bread or cake and you are uncertain whether challah was separated. Simply have in mind now to designate part of the bread as challah and leave that part uneaten.)

5. One should treat the separated portion, which is now challah, as non-kosher and destroy it. One may wrap it up carefully in two layers of aluminum foil and burn it in one’s oven or on top of the stove. In our ovens, one may burn the challah while using the oven for cooking or baking, so long as one is careful that it does not unwrap. Even if it does unwrap, it will not prohibit anything baked in the oven at the same time; however if it touches the oven itself, that part of the oven will require kashering. Because of the latter concern, some people prefer to wrap it carefully and respectfully place it in the garbage.


To answer Mrs. Ginsburg’s question how she should separate challah, we must first appreciate that there is no mitzvah to take challah if one is baking only a small amount of dough. Referring back to our Pasuk, we will see why this is true.

When the Torah required separating challah from “your kneading bowls,” to whom was the Torah speaking? Obviously, the generation living in the Desert, who were eating man. The Torah (Shemos 16:32) tells us that each individual gathered one omer of man each day in the Desert. Since the “bowl” used by the Jews in the Desert contained one omer, we know that this is the size bowl that the Torah is describing.

How big is an omer? The Torah (Shemos 16:36) teaches that this was one-tenth the size of an eifah, but that does not help us if we do not know the size of an eifah. The Shulchan Aruch (Yoreh Deah 324:1) rules that an omer contains 43.2 eggs. By the way, the gematria of the word challah is 43, and the last letter of challah is a hei, whose gematria is five. This is a good way to remember that the minimum size of separating challah is a dough the size of 43 and 1/5 eggs (Shach 324:2).

However, today we are uncertain how much dough this means since eggs vary tremendously in size. For our purposes, I am suggesting an estimate. We will assume that less than eight cups of flour does not require separating challah, and that one should not recite a bracha before separating challah unless one uses at least five pounds of flour. Any amount in between requires separating challah but without reciting a bracha. These figures are estimates and your Rav may give you different amounts.

If you ask me why I gave the first measurement in cups and the second in pounds, the answer is very simple. Cups are a less accurate measure than pounds, but more commonly used. If a woman knows that every time she uses eight cups of flour she should take challah without a bracha she is unlikely to miss taking challah when necessary. On the other hand, a bracha requires a more accurate measure, and most poskim require a bracha over dough made from five pounds of flour, although many poskim rule that one should recite a bracha even if using less.


One recites the bracha only when certain that the dough is large enough to fulfill the mitzvah. If the batch is too small to fulfill the mitzvah, then a bracha would be levatalah, in vain. On the other hand, if one is required to separate challah, then one may not eat the bread without separating challah. Since it is uncertain exactly how much flour requires challah, we separate challah on any dough without a bracha when it is questionable whether one is required.

Preferably, one should try to recite a bracha before performing a mitzvah. Therefore, it is preferred to make a batch large enough to separate challah with a bracha. However, if one does not need such a large amount and it will go to waste, one should make a smaller dough and separate challah without a bracha (assuming that the batch contains at least eight cups of flour). It is preferable to bake fresh bread for every Shabbos rather than bake a double-batch one week and freeze half for the next week, unless the frozen bread tastes as good as the fresh variety.

We have now answered Shaylah #2, the dispute between Mrs. Bracha and Mrs. Ginsburg whether one should try to combine doughs to recite a bracha on the mitzvah. Indeed, one should.

Furthermore, one may not deliberately make small doughs to avoid taking challah altogether (Gemara Pesachim 48b; Shulchan Aruch Yoreh Deah 324:14). Therefore, someone making small batches should combine them into one larger batch in order to fulfill the mitzvah.


How does one combine different batches of dough or bread?

There are two general ways to combine different doughs into one “batch” in order to perform the mitzvah of separating challah. The first is by actually combining two doughs together; the second is by using a vessel to combine doughs or breads into what is now considered to be one batch.


One can combine two doughs by touching them together sufficiently that parts of one dough will join the other dough when separating them (Shulchan Aruch, Yoreh Deah 325:1 and Taz). This sticking together is enough to make the different batches considered as one.

Thus, Mrs. Ginsburg could combine her two doughs by touching them until the doughs stick together. Although this is often a simple way to combine two doughs, Mrs. Ginsburg pointed out that this approach is impractical when her doughs are mixed in two separate bowls. However, a simple solution is to wait until after the doughs rise and then to place them both on the board or tray for braiding. At this point, she should touch the doughs together until they stick to one another and become considered one dough.

“Does this mean that I can never take challah until my dough is removed from the bowls?” asked Mrs. Ginsburg. “I would prefer to separate challah while the dough is still in the bowl.”

Indeed, there are two possible ways she could take challah from the dough while it is still in the bowl, although each approach has its potential drawbacks.

A. If the dough rises in the bowls until it is high enough that one can touch the two doughs together, one may separate challah from one dough for both of them after sticking the two together. Of course, this is only possible if both doughs rise until they are higher than the top of the bowl.

B. A second approach involves placing the two bowls in a sheet or tablecloth in a way that the two bowls are touching while inside the sheet or cloth (Mishnah Berurah 457:7). Then fold the sheet or cloth over the bowls until it covers the doughs, even partially. I will explain shortly why this combines the doughs together. For reasons beyond the scope of this article, I prefer method “A” to method “B.”


Another method of combining either dough or bread from small batches into one large batch to fulfill the mitzvah of challah is to place them together in a basket or other vessel (Mishnah Challah 2:4; Gemara Pesachim 48b).

Why does a basket make two or more different batches into one batch? Refer back to the Pasukim that I quoted earlier:

Pasuk 19: And it will be when you eat from the bread of the land, that you should consecrate a special portion for Hashem’s sake.

Pasuk 20: The first of your kneading bowls is challah; you should consecrate it just as you consecrate part of your grain.

I noted above that Pasuk 19 refers to separating challah when you eat bread, whereas Pasuk 20 mentions taking challah from your kneading bowls, which implies that we already separated challah when it was dough. Why does the Torah teach us to separate challah from bread when we already separated challah when it was being kneaded? The answer is that sometimes a dough is too small to require separating challah, but placing the baked bread (from two or more such doughs) in a basket will create a batch large enough to perform the mitzvah!


If one does not want to combine two doughs, for example, if one dough is whole wheat flour and the other is white, or one is bread dough and the other pastry, then combining the two batches does not work (Shulchan Aruch Yoreh Deah 326:1). These batches remain separate unless one actually mixes the two doughs together. Thus, even if one touched together hamantashen dough with bread dough and the two combined have the requisite amount to separate challah, they do not combine.

At this point, we can answer Mrs. Ginsburg’s shaylah, about combining two batches of dough mixed in separate bowls. I have suggested two methods whereby one can combine the two batches into a five-pound batch and recite a bracha before the separating:

1. Take the different doughs and touch them together until the edges stick to one another. Do this either while the dough is in bowls or any time afterwards before the bread is baked.

2. Place the doughs or breads together inside one basket, cloth, or vessel. Since they are all inside one container, this combines them into one batch. Preferably, the dough or breads should all touch one another (Mishnah Berurah 457:7).

We can now analyze Mrs. Lowenstein’s question whether her freezer combines the breads into one batch that requires her to separate challah?


Previously, we discussed how one can combine to batches together for mitzvas challah by placing them into one basket. Does putting breads or hamantashen from many small batches into the freezer together create a mitzvah of separating challah?

The Gemara (Pesachim 48b) teaches that a table with a rim around it combines small batches of bread together to create a mitzvah of challah. Thus, it seems that a basket is simply an example. However, many Rishonim imply that the mitzvah of challah is created by a vessel only while in the process of baking bread, but not afterwards (Rashi, Pesachim 48b; She’iltos #73; Eimek Shei’lah who explains these opinions meticulously). However, the Rosh (Beitzah 1:13) implies that if a large quantity of bread is mistakenly placed into one vessel later, it will become obligated in challah at this point, and therefore he recommends combining all the doughs together earlier and separating challah. Shulchan Aruch (Orach Chayim 457:1) implies that he rules like the first opinion, unlike the Rosh.

Although some poskim suggest that a freezer will combine just as a basket combines, most contemporary poskim rule that this is not a concern for a variety of reasons. These reasons include: 1) This takes place long after you finished making the bread. 2) You have no intent to combine the doughs together. 3) A freezer may not be considered a vessel at all because of its size and weight. 4) The doughs are all bagged before they are placed inside the freezer (see Machazeh Eliyahu #l11; Shu’t Nimla Tal).

We can now answer questions 1 and 3 that we posed at the beginning. 1) One should indeed try to combine different batches of dough or bread in order to separate challah from them, and in order to be able to recite the bracha. 3) Although a vessel or tablecloth will combine different doughs into challah, a freezer does not create a concern that requires separating challah, nor does it combine batches for challah taking.

Having discussed the halachic details of this mitzvah, it is worthwhile taking a glimpse at the following Medrash that underscores its vast spiritual significance: “In the merit of the following three mitzvos the world was created – in the merit of challah, in the merit of maasros, and in the merit of bikkurim” (Breishis Rabbah 1:4). Thus, besides gaining us eternal reward, this easily kept mitzvah helps keep our planet turning.
