Definition
- The three criteria necessary in order to violate the biblical prohibition of Losh are:
- there is a mixture of two ingredients,
- one of the ingredients is powdery like flour, chopped (like chopped eggs), or thick (like jam), and
- the mixture forms a thick dough-like substance [1]
- It’s forbidden to mix two ingredients when they combine either (1) because one of them is a liquid, (2) there is liquid naturally present in one of the ingredients (such as a fruit), or (3) one of the ingredients is a thick coagulating substance (such as mayonnaise). [2]
- Kneading flour and water is a violation of the biblical prohibition of Losh (kneading).[6]
Combining the Ingredients
- Just as it is forbidden to knead two ingredients together so too it is forbidden to pour one onto the other so that they will mix automatically. Therefore it is forbidden to pour water onto flour or flour onto water on Shabbat.[7]
Bar Gibul
- There is a distinction between something which is bar gibul, meaning mixed easily and something which is lav bar gibul which doesn't mix easily.[8]
a Mixture Which Was Mixed Before Shabbat
- Even if the two ingredients were poured one upon another before Shabbat it is forbidden to knead them together on Shabbat.[9]
- If two ingredients were kneaded together before Shabbat, it is permissible to add liquid and even mix slowly.[10]
- Therefore, if oil separated from peanut butter and floats on top of it, it's permissible to remix it. It would even be permissible to add more liquids. Adding more solids, however, is forbidden.[11]
Making a thin mixture
What is a thin mixture?
- Ashkenazim hold that anything which pours from one vessel to another is considered a thin mixture. [12] Sephardim hold that even if it pours from vessel to vessel it’s not considered a liquid unless it is drinkable and not just meant for eating. [13]
When is it permissible to make a thin mixture?
- According to Ashkenazim, it is only permitted to mix a thin mixture if one both changes the order of putting in the ingredients and stir it in a different way. [14]
- According to Sephardim it’s permitted to mix a thin mixture if one either changes the order in which one puts in the ingredients or if one changes the way one mixes. [15]
What is considered a change in the order?
- A variation in the order means that if one normally puts the solid ingredient in first, then one should put the liquid ingredient in first, if one normally puts the liquid in first, then put the solid in first. If there is no set order then one should put the solid in first. [16]
- If one doesn’t know what order is the common practice one may assume that the instructions on the package is the common practice and one may reverse the order of that. [17]
- If there’s no clear common practice one such put the solids first and then the liquid. However, one should only use this leniency in cases of necessity. [18]
- If there is no liquid but only a coagulating substance (ex: mayonnaise) there is no need to change the order in combining the ingredients. [19]
What is considered a change in mixing?
- If possible one should stir it with one’s finger or mix it by moving the bowl. If that’s not possible one should use an instrument but mix in a criss cross manner and preferably remove the utensil after each stroke. [20] According to some poskim, mixing it with the handle of the spoon or knife is sufficient.[21]
Making a thick mixture
- If one needs to prepare a thick mixture on Shabbat and one can’t make it before Shabbat, then before Shabbat one should mix in some liquid so that all of the solid is saturated and then on Shabbat one may mix in more liquid as long as this doesn’t cause the mixture to thicken and one also does the two variations above (switch order and way it’s mixed). [22]
- If there is a need to prepare a thick mixture on Shabbat and one can’t add the liquid before Shabbat (such as if one needs fresh food for a baby) then one may make the mixture on Shabbat if one is careful about the two variations above (switch order and way it’s mixed). [23]
Making a watery mixture
- It is permitted to mix solid particles with a lot of liquid if it will result in a very watery mixture such as making baby formula from powder and water. Nonetheless, one must be careful to pour in the liquid at once and not gradually. [24]
Cooked Foods
- Many hold that there is no prohibition of losh on a cooked food. Therefore, one may mix margarine into a baked potato or mix cinnamon or raisins into a cooked cereal (like oatmeal).[25]
- Some say that it is permitted to mix a little amount of liquid with instant coffee or sugar and mix it gently. [26]
Practical Examples
Mashing a Banana
- It's permissible to mash a banana with the handle of a fork or spoon.[27]
- However it is forbidden to add any liquid to such a mixture.[28]
Making Vegetable Salad
- The prohibition of kneading does not apply to large chunks of food which will be distinct even after being mixed. [29]
- For example, one may dress a salad (with oil, vinegar, mayonnaise, and seasoning) if the vegetables are slightly large pieces. [30]
- When making salads with mayonnaise, such as egg salad or mayonnaise with vegetables, one should first put in the mayonnaise and then the salad since that is different than the way one would do it during the week. Also, one should mix with a shinuy such as criss-cross and not in a circle.[31] Some say that it isn't necessary to make a shinuy in the pouring.[32]
Making Egg Salad
- To avoid all issues it’s preferable to make egg salad before Shabbat. However, if one didn’t, one may do so on Shabbat in the following manner: One may peel the eggs right before the meal and then mash them even with the prongs of a fork. Then peel the onions right before the meal and cut them in slightly large pieces and then mix it. The minhag is to mix in oil without any variations, however, it’s proper to make above variations (in order of putting in ingredients and way of mixing). [33]
- One can mix in the cooked potatoes using the handle of a fork, or if the potatoes are very soft because of the cooking one may mix it with the prongs of the fork. [34]
- If an egg shell got mixed into the salad one may only remove it together with a bit of other food, but preferably one shouldn’t remove the egg shell but just eat around it. [35] See Borer.
Instant Mashed Potatoes
- One may not make instant mashed potatoes as it is considered a thick mixture. [36]
Instant Pudding
- One may not make instant pudding as it is considered a thick mixture. [37]
Mayonnaise
- According to Ashkenazim, one may not make thick mayonnaise on Shabbat and thin mayonnaise preferably should be made before Shabbat.[38] According to Sephardim one may make mayonnaise on Shabbat if one is doing so in order to eat it immediately. That is, it is permitted to mix eggs, oil, mustard, sugar, and some salt. Also, one shouldn't mix them vigorously.[39]
Drinks
- When one substance becomes completely absorbed into the other so that there isn't a noticeable difference in the consistency of the liquid, there is no problem of lisha. For example, one may add instant coffee or hot cocoa to a cup of hot water (as long as there is no problem of bishul).[40]
Gaucamole
- If one wants to make fresh guacamole on Shabbos one should mash the avocado with the handle of the spoon or the like. To add in onions, tomatoes, lemon juice, or spices and avoid the issue of losh, one would have to use a double shinui. That is, one should put in the lemon juice or spices first and then the avocado and mix it with the back of a spoon or with a criss-cross action.[41]
Other Examples
- It is forbidden to pour water on sand. Therefore, children playing in a sandbox should not pour water into it.[42]
- If one needs to wash his hands or urinate on the ground, he should look for an area without any loose sand or dirt. In case of need however, one may be lenient.[43]

- ↑ As is evident from gemara Shabbat (18a), mixing flour and water is a violation of Losh (Menuchat Ahava 9:1). Chut HaSheni (Shabbat vol 1 pg 105) defines Losh as the prohibition to mix two ingredients using a liquid to form a dough.
- ↑ In Gemara Shabbat 18a there is a dispute whether one is liable for violating Losh by simply pouring liquid into flour or only if one both pours in the water and mixes it. The majority of the Rishonim (Rif, Rambam, Rosh, Ramban, and Ran, cited by Shaar haTziyun 321:57) hold that one isn't biblically liable until one has both poured in water and mixed it into dough (Mishna Brurah 321:50), nonetheless, Mishna Brurah 321:57 (quoting the Magen Avraham) there is a rabbinic prohibition even for just pouring liquid into flour or the opposite. This is also the ruling of Shemirat Shabbat KeHilchata 8:5, 39 Melachos (by Rabbi Ribiat, vol 1, pg 531), and Menuchat Ahava 9:1.
- ↑ The gemara Shabos 155b distinguishes between what is known as a Bar Gibul as opposed to a Lav Bar Gibul. The basic distinction between the two is that a bar gibul is something which mixes easily upon addition of liquid, such as fine powder, flour, or sand, while a lav bar gibul is something that does not.
- However, within the very definition of a lav bar gibul, there is a machlokes as to what its halachic status is. Rambam Shabbos 8:16 suggests that because these substances, such as ash or coarse sand never truly fuse with the substance it is being mixed with even when water is added and kneading is done, it is therefore not subject to the melacha altogether. Nonetheless, the Rambam (Shabbos 21:34) writes that would be a rabbinic concern of appearing as lishah. Mishnah Brurah 321:50 quotes this.
Most poskim (Tosfos, Rosh, Rashba, Raavad, and Ran cited by Shaar hatziyun 321:60) however, understand that a lav bar gibul is still subject to the melacha of losh, and therefore in certain circumstances may be dealt with in an even more stringent manner than a bar gibul material, for it would be culpable simply upon addition of water, without any kneading, considering that the kneading does not accomplish anything of significance.

- ↑ Shulchan Aruch 321:19 rules based on the Rambam (responsa 109) that one may stir a dish of grits and meat and mash them so that they dissolve and form into one mass. Bach 321 questions the Rambam and says that one may only stir gently. Magen Avraham 321:28 agrees. However, the Taz 321:14 writes that since the meat and grits have been mixed with water and cooked before shabbos, there is no problem of losh in mixing it again. Chazon Ish 58:9 agrees if there is some liquid there from before Shabbos, one may then put in more on Shabbos. Biur Halacha 321:14 s.v. shema adds another reason to be lenient with stirring food that is already cooked; since it is already fit for eating, the kneading becomes part of the process preparing it for eating, derech achila, and would be permitted if you stirred a little bit at a time. Mishna Brura 321:77 advises following the strict views of the Bach and Magen Avraham. Chazon Ish 58:9 allows stirring even vigorously. 39 Melachos (pg. 540) writes that you can mix margarine into a baked potato. Shemirat Shabbos KeHilchata (8:24) agrees and adds (8:25) that you can mix cinnamon or raisins into oatmeal.

- ↑ Shemirat Shabbat KeHilchata 8:3 writes that it's permissible in terms of Losh even though it sticks together because it is not composed of two ingredients. Nonetheless due to a concern of Tochen one must use the handle of a fork or spoon. A similar analysis is found in Sh"t Igrot Moshe 4:74 (Losh #2 at the end) and Chazon Ish (OC 58:9 s.v. Yesh).

- ↑ Or Letzion 2:33:3 writes that when making salad with mayonnaise one should first put in the mayonnaise and then the salad since that is different than the way one would do it during the week. Also, one should mix with a shinuy such as criss cross and not in a circle. Rabbi Langer (Chicago Kollel Devarim 5769) cites Shemirat Shabbat Kehilchata 8:33 as holding that preferably a person should do both shinuyim when making egg or tuna salad.
- ↑ Orchot Shabbat 1:6:18 cites the Shevitat Hashabbat (Intro to Losh n. 6) who limits losh to water or liquids that permeate the solids to consolidate them and it wouldn't apply to thick fatty liquids such as mayonnaise. Orchot Shabbat is willing to rely on this opinion with respect to pour the ingredients together since anyway we really hold like the opinion that losh is violating by kneading and not pouring (Rabbi Yosi Bar Yehuda). He concludes that Rav Shlomo Zalman Auerbach liked this approach.

- ↑ Rambam (Shabbos 8:16) based on the gemara Shabbos 18a writes that kneading water and dirt is forbidden from the torah as a tolada of losh. Based on that, Shemirat Shabbos KeHilchata 16:4, Children in Halacha (Rabbi Simcha Bunim, pg 137-8), and 39 Melachos (Rabbi Ribiat, vol 2: pg 253-254) write that children who are playing in a sandbox may not pour water into it.
The Gemara (155b) cites a dispute as to when one would have violated losh. According to Rebbi, pouring water into flour is enough, while according to Rabbi Yosi bar Yehuda, one isn’t liable until he kneads them together to form dough. The Rif (67b), the Rambam (21:34) and the Rosh (24:3) rule like R’ Yosi bar Yehuda that it is only forbidden midirabanan to pour water without mixing it, while the Yereim (Ch. 274, 133b), the Teruma (Ch. 220), the Semag (Prohibition 65, lash) and the Semak (Ch. 280) hold like Rebbe. The primary opinion of Shulchan Aruch 321:16 is like R’ Yosi, however, he also cites the opinion of Rebbi. Chacham Ovadia Yosef (Livyat Chen 67) and Menuchat Ahava (vol. 2: 9: note 9) are lenient. Rama is strict and this view is accepted by the Ben Ish Chai (Mishpatim 18) and Kaf Hachayim (324:14).
- ↑ The Mishna Brurah 321:57 cites the Magen Avraham that it is forbidden to urinate on mud because of losh and the same would be true of loose dirt or sand, even though it is unintended. He also cites the Beit Meir who is lenient in a case of need, to urinate even upon mud since he rules like R’ Yosi Bar Yehuda (cited in Masechet Shabbat 155b) that it is only dirabanan if you don't mix but merely pour water. Mishna Brura concludes that one may be lenient in case of need when the mud doesn’t belong to you, since one doesn’t benefit from the dirt mixing with the liquid. Kitzur S”A 80:14 and Menuchat Ahava 2:9:2: pg. 287 agree that if possible one should be careful. See also Ketzot Hashulchan 130:8.
