Bishul Akum (Hebrew: בשול עכו"ם, tran. cooking of a non-Jew) is a rabbinic restriction that forbids a Jew from eating many foods that a non-Jew cooked. The reason for the restriction is to prevent intermarriage and to avoid eating non-kosher ingredients mixed in. There are many leniencies that relate the quality of the food or the significance of the cooking for the particular food in question. Additionally, a Jew is partially involved in the cooking process this can alleviate the issue of bishul akum. This is a key reason for the need to have a hashgacha on many foods even though all of the ingredients are kosher.

- The rabbis enacted a decree forbidding food that was cooked by a non-Jew. However, it is permitted to derive benefit from the food.
- There are a number of reasons for this restriction. Some early commentators explain that the rabbis wanted to prevent socializing with non-Jews, which might lead to intermarriage. Others think that the motivation for this restriction is that we are concerned that if the Jew often eats the non-Jew's food, the non-Jew might later serve a non-kosher food item to the Jew. Most rabbis agree with the first reason.
- The rabbis were more stringent with these laws of bishul (cooking) than with bread of a non-Jew.
- There are two basic exceptions to the restrictions. A food that falls into either of these two categories is not subject to the laws of bishul akum and may be eaten by a Jew even initially.
- A food that can be eaten raw may be cooked by a non-Jew for two reasons. First, the cooking does not really improve the food because it can be eaten raw (and not considered cooked). Second, food which is edible raw is not an important food and one would not invite someone to his home to eat such foods. Examples of such foods are beets, cheese, fruits, honey, juice, ice cream, milk, (this will be discussed in a later issue), sugar cane, zucchini and other vegetables, and water. Examples of foods that are not edible raw are asparagus, cauliflower, chicken, meat, potatoes, (this will be discussed in a later issue) and pumpkin.
- The prohibition of bishul akum is limited to foods which are served on a king's table (oleh al shulchan melachim) and accompany bread (such as meat, eggs, or fish) or as an appetizer. Only these types of foods are served at social gatherings and only then is there the concern for intermarriage. When there is no invitation, there is also no concern that the Jew will become used to eating the non-Jew's food, and therefore, there is no concern that the non-Jew might later serve the Jew non-Kosher.
- Many say that any food that is fit to be served on a king's table is subject to bishul akum even if it is not eaten with bread. Others say that the above stipulation is to be taken literally and even an important food is only prohibited if it is eaten with bread. The accepted custom follows the stringent opinion.
- There is a third, somewhat obscure exception, which permits food which does not change when it is cooked. However, most poskim maintain that this may not be relied upon to permit bishul akum.
What Does "Eaten Raw" Mean?
- The poskim debate the definition of "eaten raw." Some say that it depends on each individual's eating habits. However, many say that it follows the custom of most people. Accordingly, if most people eat a food raw then one may eat it if a non-Jew cooked it. Even if he personally would not eat this food raw, his eating habits are insignificant in determining a norm of eating habits for most people.
- A food which can only be eaten raw in difficult circumstances is not considered halachically edible raw, while others argue and hold it is still considered halachically edible raw.
- If it is common to eat the item raw with other ingredients, then the raw item is still considered edible raw. A food which was edible raw while fresh is not considered edible raw after it dries out.
- Some say that bishul akum doesn't apply to corn because it would be normal to eat corn raw, however, it is just uncommon, however, others hold that bishul akum does apply to corn since it isn't eaten raw.
"Fit to be Served on a King's Table"
- We mentioned earlier that food which is fit to be served on a king's table is subject to the halachos of bishul akum. This term requires clarification. What if a king eats it for breakfast but would not eat it for supper? Some say that this refers to food that would be served at a royal dinner; the prevailing opinion is that it refers to anyone of stature, not just a king. Others say it means food which would be served at a state dinner, while some apply it even if a food is eaten by a king at breakfast (this is not the halacha). Others are of the opinion that it refers to a food that one would serve on Shabbos to invites guests, or food served at a fancy meal in honor of a mitzvah. Harav Yisroel Belsky and is the OU policy hold that it refers to food served at a wedding smorgasbord. Examples of foods which do not fit the above and are permitted are: chickpeas, corn, snacks, Rice Krispies, and popcorn.
- Is "Fit to be Served on a King's Table" according to the category or specific food? Some poskim hold that if a certain type of food can be prepared in a way that could be served at a king's table, then any dish prepared from this food falls under the problem of bishul akum, even if this particular dish would not be served at the king's table. However, most poskim disagree with this position and maintain that each dish must be evaluated individually. Accordingly, if a specific potato is prepared in a way that it is fit for a king's table then only that type of potato is a problem of bishul akum. This opinion is followed by most kashrus agencies.
- If a food would only be fit for the king's table after certain spices and seasoning were added, it is still considered fit for the king's table even without the spices.
- Bishul Akum applies to instant rice which was cooked by the non-Jewish manufacturer. Parboiled rice, however, which requires further cooking to be edible is not Bishul Akum at the time of manufacturing and need to be finished cooking by a Jew.
- Many hold that Bishul Akum does not apply to potato chips since in that particular way of preparing a potato it isn't fit to be served on a king's table. Some are strict about this and won't eat pringles with an OU because of the bishul akum issue.
- Many hold that the definition of fit for a king's tables depends on the current custom and not a previous custom.
Product Shipped From one Place to Another
- If a non-Jew cooks a food which is edible raw then it is permitted even if it is shipped to a country where it is not eaten raw. This is not a common issue as a food which is edible in one country is usually edible in a different country as well.
- If a non-Jew prepared a food which is not edible raw in a country where it is not served on a king's table and shipped it to a country where the food is fit to be served on a king's table the food is forbidden because of bishul akum. If the situation is reversed, and a non-Jew prepared a food which is not edible raw and it is fit to be served on a king's table in that country, then the food is forbidden even if it is shipped to a country where it is not eaten on a king's table.
- There is a discussion in the poskim if an important person should go beyond the letter of the law regarding the laws of bishul akum. Some poskim say that such a person should refrain from any food cooked by a non-Jew even if it can be eaten raw, if it is fit to be served on a king's table. The reason is that if one sees an important person being lenient even though it is permitted strictly speaking, the onlooker will potentially be more lenient in a circumstance where it can be forbidden.
- If it is eaten raw and fit to be served on a king's table one should be stringent. However, others disregard this concern, and the custom seems to follow the latter opinion. Even the stringent opinion makes allowances for health reasons (see below).
- A food which is fit to be served on a king's table and is not eaten raw is still not a concern of bishul akum if it is eaten for health reasons. It is not a "chashuva" food, and sharing it will not lead to closeness with a non-Jew.
Types of Food
- The consensus of the poskim is that there is a concern of bishul akum with beverages (i.e. soup) if one cannot drink it without cooking it or it is fit to be served on a king's table.
- A food that is forbidden because of bishul akum and placed into the freezer is still forbidden even though it is inedible while it is frozen. By the same token, if a Jew cooked food and froze it, there is no concern if a non-Jew heats up the food.
- Potatoes which were milled or pureed and then dehydrated to be used for producing other food is subject to Bishul Akum since it is edible without further cooking such as adding lukewarm water.
- There is a discussion among the poskim if canned food is subject to the halachos of bishul akum. Food which is cooked before it is canned and is just put in a can for storage would be forbidden. However, one could argue that food cooked in a can is not fit to be served on a king's table. The custom seems to treat canned goods as a concern of bishul akum (if the food is not edible raw) even if it is cooked with indirect steam. However, this can be used as an additional factor to be lenient in certain cases.
- There is a discussion in the poskim if food cooked by a non-Jew renders the pot treif. Some poskim say that no hagalah (kashering) is required. Some explain that the main reason for the issur of bishul akum is because of intermarriage, and there is no socializing with flavor absorbed in the pot. However, many poskim maintain that hagalah is in fact required, and this is the overwhelming custom. The reason is that the food itself becomes forbidden, and the blios (absorption) from the food are considered as forbidden foods. This applies even if the utensils were not used within twenty-four hours (eino ben-yomo) in which case the taste of the food is pogem (ill tasting). Nonetheless, one can do hagalah (after waiting twenty-four hours) for an earthenware utensil (which we normally do not kasher) three times and use it for kosher food. This is common if a non-Jew used a crock-pot to cook food.
- An interesting question arises regarding kashering the utensils of a convert which were only used for kosher food. It would seem from the language of the Shulchan Aruch (when he discusses the obligation to kasher from bishul akum) that he does not require kashering. However, when the question arises one should discuss it with a competent Rav.
Doubts and Mixtures
- The halacha is that anytime one has a doubt whether a Jew stoked the coals, or if a food was cooked 1/3 by a Jew, then we can be lenient. Some even say that if one is not sure whether a particular food is subject to the laws of bishul akum he may be lenient since the entire prohibition is rabbinic (Klalei_Halacha#Safek_Derabbanan_Lkula). There is a discussion if we can be lenient if one is unsure if a food is fit to be served on a king's table. Some poskim are lenient even if one can verify the status, but the custom is to be stringent.
Rov or Shishim
- Most poskim are of the opinion that bishul akum is nullified in a simple majority (botel b'rov) while some maintain you need shishim (60 times). Sephardim hold you need 60 times but if you have majority and not sixty you can add more permitted ingredients in order to nullify it.
Mixing Edible with Non-Edible Raw Food
- If food which is edible raw is mixed with food that is not edible raw, the mixture is not subject to the halachos of bishul akum if most of the ingredients are food which can be eaten raw. Some permit even if it is half and half (this will be discussed in a later issue). Some say that the five grains are considered the main ingredient as is the case in hilchos berachos.
- Some say this is only permitted if the food which is not edible raw is not recognizable in the mixture.
- Sometimes, a food may be eaten raw but is a tafel to the main food which has a concern of bishul akum (not eaten raw). The question is if the food eaten as a tafel is subject to the halachos of bishul akum. The rules here follow the same rules as berachos. A food which is mixed to the same degree where it is considered mixed in regard to the halachos of berachos would not be permitted because of bishul akum. For example, if peas (edible raw) are mixed with other food then there would be a bishul akum concern for the peas as well.
Forms of Cooking
- Some poskim hold that there is no prohibition of bishul akum when cooking in a microwave, while others disagree.
Jew Watching non-Jew
- A prohibition remains even if a Jew observes the cooking process and ensures that nothing is added. The reason is that the main reason for the issur is because of intermarriage, and standing over a non-Jew does not mitigate this factor.
- Ideally, according to Sephardim, one should not eat in a restaurant where the food was not put on the fire by a Jew, regardless of who lit the flame. Rav Ovadia Yosef articulated a leniency to eat in a restaurant or hotel with Ashkenazic hashgacha that only makes sure that a Jew turns on the fire but not that a Jew is involved in the cooking. One should ask a qualified rabbi regarding how to apply this leniency in various situations, such as Jewish homes where the maid did some cooking, Shawarma cut by a non Jew, etc.

- Tiferet Yisrael (Avoda Zara Yachin. 2:52) writes that when judging whether something is fit for a king we judge the type of food. Teshuvot Vhanhagot 1:438 agrees and forbids potato chips.
- One proof is that the Iser Vheter that is cited and accepted by the Shach (113:2) writes that intestines are forbidden because of Bishul Akum even though they aren’t fit to serve a guest (S”A YD 101:5). Since meat is important we judge all meat as fit for a king’s table even the parts which are very low quality. This is echoed by the Pri Chadash 113:2 and Aruch Hashulchan 113:10. Rav Pesach Falk (author of Machazeh Eliyahu, in Am Hatorah 5754 p. 75) argues with the Tiferet Yisrael based on a number of proofs.
- Another factor to use to permit potato chips is that usually they aren’t eaten with bread and some poskim hold that any food which isn’t eaten with bread isn’t included in Bishul Akum. Pri Chadash 113:3 is lenient. See Darkei Teshuva 113:12 for those who are lenient. Chayei Adam 66:1 and Yechava Daat 4:42 don’t hold of this Pri Chadash. Rav Heinemann is lenient for potato chips since they are not eaten for a meal at all. Rav Shlomo Machpud (Daat Kashrut 5762 p. 136) agrees.

The reason for this is since the food is edible raw in one place there is no certainty that it will not be edible raw in the place where it is shipped since it is many days from when the food is made and the food may be dry.

- Rav Shlomo Machpud in Daat Kashrut 5762 p. 136 writes that since the potatoes were steamed and then pureed they are ready to be eaten with simply adding lukewarm water and therefore forbidden. He cites Rav Masas in Shemesh Umagen 2:44 who is lenient but also cites Rav Mordechai Eliyahu who was strict. Rav Masas argued that since the pureed needed further processing it is like the original cooking wasn't ineffective.

- Refer to Bishul Yisroel (teshuvos) pages 46-47, Teshuvos V’hanhagos 3:247. Also see Bishul Yisroel pages 34-36. Some are lenient because many products do not get changed when cooked in a can (Aleh Ezra Y.D. 5).
- The Shach 113:20 says cooking for herself is more stringent because it is unlikely that a Jew will intervene. Refer to Prisha 113:17, Chochmas Adom 66:11. See Shulchan Melachim 2:pages 959-957.

One doubt is if such utensils require hagalah and the other doubt is if there is bishul akum in a Jew’s home (Halichos Olom 7:page 104:footnote).

- Refer to Hagalas Keilim 10:footnote 11, Chelkes Binyomin 113:136.
- Divrei Dovid 2:20 proves the Shulchan Aruch Y.D. 113:3 holds that bishul akum isn't nullified by a majority. He cites this approach from the Bear Sheva 19, Minchat Cohen 1:1, Pri Chadash 99:17, Maharashdam 41, Kahal Yehuda 113:2, Misgeret Hashulchan 113:2, Ayin Hamayim 112:11, Kiseh Eliyahu 113:2, Maharam Shik 134, and Yeshuot Yakov 113:3.

-  writes that Shevet Halevi 8:185, Shraga Hameir 6:52:3, and Rav Elyashiv (Shvut Yitzchak v. 6 p. 61) hold that there is bishul akum for microwaves.
- The OU writes that it is a dispute whether there is bishul akum when cooking in a microwave since it is an innovation or perhaps it is considered a normal form of cooking today.
