A Brief Intro to “Kosher for Passover” and the Pesach Holiday

By: Rabbi Dovid Heber

January 2025

Passover is a joyous eight-day holiday celebrated in early spring. The name Pesach is derived from the Hebrew “to pass over,” since G-d “passed over” the homes of the Jews during the tenth plague on the Egyptians.

Passover commemorates the redemption of the enslaved Israelites from Egypt and the forging of the new Jewish nation. It has a distinctive set of laws and customs, the highlight being the Seder, a festive meal on the first two nights (only one in Israel) that includes many symbolic foods – matzah, bitter herbs, charoses – and four cups of wine. This family-centered holiday is widely observed, albeit with a diversity of beloved traditions passed down from generation to generation. Passover’s popularity is reflected in the kosher marketplace where, by some accounts, 40% of sales revolves around this holiday.

Passover involves a unique set of kosher laws, chief among them the prohibition to eat any […]

The 10 Commandments for the Prudent Passover Consumer

I. Thou Shalt Read Product Labels Carefully

Make sure a reliable Kosher for Passover certification appears on the package. Don’t assume the product is kosher for Passover just because it is in the Passover section of the supermarket.

II. Thou Shalt Beware of Look-Alikes

Often Kosher for Passover and non-Kosher for Passover products have identical packaging except for the “P” symbol.

III. Thou Shalt Know That Not All Matzohs are Kosher for Passover

Stores often do not remove chometzdik matzos from the shelves even after the store is stocked with Kosher for Passover products!

IV. Thou Shalt Know Thine Personal Kashrus Level

Not all kashrus certifications are created equal. A knowledgeable kosher consumer reduces the chance of buying Kosher for Passover products that may not qualify for a consumer’s personal kosher or Passover kosher standards.

V. Thou Shalt Look Before You Cook!

Even with the best intentions a non-Kosher for Passover […]

Preparing/Kashering the Pesach Kitchen

As the Yom Tov of Pesach nears, and the diligent balabusta begins to tackle the challenge of preparing the kitchen for Pesach, undoubtedly the light at the end of the tunnel is beginning to shine. Although moving into a separate Pesach home sounds very inviting, such luxuries are often not affordable and definitely not in the Pesach spirit. Among the basic mitzvos of the chag is the mitzvah of tashbisu se’or mibateichem, ridding one’s home and possessions of chometz. However, if we are to use kitchen equipment, utensils, or articles that can be found in our kitchen year-round, it may be insufficient to just clean them thoroughly. One is forbidden to use these items unless they have been especially prepared for Pesach. This preparation process is known as kashering.

The Torah instructs us that the proper kashering method used to […]

Utensils that are used during the year with chometz are forbidden to be used during Pesach without kashering them according to Halacha. From the time it is prohibited to eat chometz on Erev Pesach, it is forbidden to use the utensils without kashering them according to Halacha. The proper kashering method used to rid a vessel of chometz is dependent upon the original method of food preparation through which chometz was absorbed into the vessel.1We do not recite a bracha when kashering an item since it is a negative commandment not to consume the taste of non-kosher food.2Sephardic custom is that the method of kashering depends upon the most common usage of the vessel. Therefore, it is sufficient to pour boiling hot water […]

The Mitzvah of Tevilas Keilim

Introduction:
In His infinite wisdom, Hashem Yisborach has spiritually elevated the mundane activity of eating and has vested it with special sanctity, kedusha. The food we eat must be kosher, the table upon which we eat our meals represents the holy altar, the mizbeach. Similarly, the vessels and utensils (keilim) used for preparing food and for dining must be given special holiness. When these dishes and/or utensils have been previously owned by an aino Yehudi, we have to immerse these keilim, in a mikvah before their first use.

Keilim (vessels/utensils) can be categorized into three halachic groupings; utensils requiring tevila (immersion) with a brocha: utensils requiring tevila without a brocha; and utensils not requiring tevila at all. Utensils require tevila with a brocha when they have direct contact with food during preparation or meal time, […]

As is commonly known, the Torah prohibits chometz on Pesach, and the consequence of chometz consumption on Pesach is very severe. In order to distance us from the possibility of violating Torah precepts, Chazal with their supreme insight, instituted a minhag as a protective fence. The minhag to guard us from chometz violations is to refrain from consuming kitniyos on Pesach.

What Are Kitniyos?

Kitniyos are popularly defined as legumes. But what are legumes? The Shulchan Aruch, Orach Chaim 453, defines kitniyos as those products that can be cooked and baked in a fashion similar to chometz grains, yet are not halachically considered in the same category as chometz. Some examples are rice, corn, peas, mustard seed, and all varieties of beans (i.e., kidney, lima, garbanzo, etc.). The […]

Kosher for Passover Foods According to Sephardi Minhagim

Rice and all different types of legumes are permissible to eat on Pesach according to the custom of most Sephardim, as long as they are careful to check rice three times to ensure there is no wheat or barley mixed in.1
Care needs to be taken that no dust of flour came into contact with the rice (or any kosher food for Pesach). Therefore, one may use only natural, unenriched rice for Pesach, ideally a rice with a reliable Kosher l’Pesach L’ochlei Kitniyot hechsher.2
Those who refrain from eating legumes on Pesach are permitted to keep them at home; there is no need to sell legumes to a non-Jew.3
It is the Sephardic custom to use egg matzah (מצה עשירה) during Pesach. This type of matzah cannot be used to fulfill the obligation of eating matzah on the first two nights of Pesach. The bracha recited […]

To some people, the concept that there are restrictions regarding what can be fed to animals may seem amusing. They wonder, “Really now, must dogs also eat kosher?” Of course, animals don’t need to eat kosher food. However, Halacha clearly instructs people regarding what, how and when to feed them.

The Talmud Yerushalmi1 states that before acquiring an animal, one must be sure he will be able to properly provide for it. Certainly, the owner must also know the applicable halachos. The following is a discussion of some of these halachos, including the subjects of meat and milk mixtures, Pesach, buying and selling non-kosher pet food, feeding animals on Shabbos and Yom Tov, and feeding animals before you eat.

In addition to pharmaceutical companies, Rav Gershon Bess also contacts many cosmetic companies and bases the following chometz-free list on his research. L’Halacha, all non-food items not fit for canine consumption – nifsal mei’achilas kelev (i.e., something that one would not feed his dog) – may be used on Pesach.

Below are several reasons why people are strict:

A handy, printer-friendly version of this article, with useful photographs of kefula matzos, can be found here.

The production of Kosher l’Pesach (KFP) matzos involves a great deal of meticulous work. The process begins with the inspection of wheat kernels to ensure that they have not been adversely affected by moisture in the air or prematurely sprouted. Grinding of the grain must be performed according to the dictates of Halacha, which precludes any pre-grind soaking of the grain and requires special preparation of the milling equipment to ensure that no contamination exists from non-Passover flour in the grinders and filters. The KFP flour is then loaded onto trucks, either pneumatically or in bags under controlled conditions, and shipped to the bakeries.

Guide to Buying Chometz After Pesach

Updated February 2024

From a Jewish-Owned Store That Did Not Sell Its Chometz to a Non-Jew Before Pesach

The Torah forbids a Jew to own chometz on Pesach. In order to dissuade people from owning chometz on Pesach, there is a rabbinic injunction not to eat or benefit from chometz which was owned by a Jew during Pesach. Such chometz is known as chometz she’avar alav haPesach, and it remains forbidden permanently.1

For this reason, one should not buy chometz from a Jewish-owned store immediately after Pesach, unless the owner sold all chometz that he owned before Pesach to a non-Jew for the duration of Pesach and did not acquire any further chometz during Pesach. The laws of mechiras chometz (selling chometz to a non-Jew for Pesach) are complex; therefore, the sale must be made by a competent rabbi or kashrus authority.
