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 Torah term for the using or fermentation of barley, rye, oats, […]

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 […]

Quinoa, the Grain That’s Not: Then Why the Need for Passover Certification?

January 2025

Tired of potatoes, potatoes and more potatoes on Pesach? Maybe give quinoa a try.

Quinoa is one of the most nutritious foods on the planet – cooked like rice, is gluten-free and loaded with vitamins and minerals. Even NASA has considered quinoa for its long-duration planetary space flights. Quinoa has become increasingly popular in the United States, Canada, Europe, China and Japan, where the crop is not typically grown.

What is Quinoa?

Quinoa (pronounced kin-wa) is a species of seeds of the Chenopodium (or “goosefoot”) family, which includes sugar beets and beet root, and is botanically related to spinach. It was first brought to the United States from South America in the 1980s. Seeds range in color from pink and orange to blue-black, purple, and red. However, once their natural saponin coating is washed off, the seeds are pale yellow.

Quinoa has been cultivated in the Andes Mountains for thousands of years, growing […]

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.

STAR-K is not necessarily recommending ownership of pets; rather, we are providing information for those owners who require it. We […]

Bedikas Chometz Guidelines

Reviewed January 2025

Before Pesach, a person is obligated to perform bedikas chometz, a search of his house and possessions, to ensure that he does not own any chometz. The bedika should be conducted at the beginning of the night of the 14th of Nissan, immediately after tzeis hakochavim.1 If he did not do so, the bedika can be done all night. Bedi’eved, if he did not perform the bedika that night he should do it on the day of the 14th of Nissan.2

If he will not be home on the night of the 14th of Nissan, he should appoint another adult to perform the bedika on his behalf.3 If he leaves his house within thirty days of Pesach, and is not planning to return and conduct a bedika or have someone else […]

A Guide to Erev Pesach That Falls on Shabbos

Updated January 2025

A printer-friendly version of this article can be found here.

Many of us are quite familiar with the regular Erev Pesach routine: The bechorim go to a siyum, the chometz is burned, and we prepare for the Seder. However, every so often,1 Erev Pesach occurs on Shabbos and we must modify our routine. Let us review the halachos of Shabbos Erev Pesach. (After this year, it will not occur for another twenty years. The next occurrences will be in 2045, 2048, 2052, and then not again until 2072.)

Thursday – Taanis Bechorim/Bedikas Chometz

On a regular Erev Pesach the first-born males (bechorim) are obligated to fast. This year the fast is pushed back to Thursday. Those bechorim who do not wish to fast should attend a siyum. Thursday night after tzeis hakochavim (when it gets dark), one should immediately perform bedikas chometz. A bracha and Kol Chamira […]

The following contains halachic guidance concerning some of the common issues that arise when conducting a Pesach Seder. In particular, it discusses preparation for the Seder, the four cups of wine, and the obligation to eat matzah, Maror, Koreich and Afikomen. This is by no means comprehensive. For a more comprehensive guide, see HaSeder HaAruch by Rabbi Moshe Yaakov Weingarten (three volumes, 1431 pages).

Preparations for the Seder

A person should complete all of the necessary preparations for the Seder on Erev Pesach to enable him to start the Seder without delay.1 (If Erev Pesach falls on Shabbos, he cannot prepare for the Seder on Erev Pesach since he may not prepare for Yom Tov on Shabbos.)

The following preparations should be made prior to Yom Tov:

How to Check Matzos

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.

A bakery which has been kashered for Pesach will have already prepared special water (mayim shelanu) to be used for Pesach matzos. Hand matzah bakeries do not use regular municipal water for fear that the […]

Machine Matzos: Timing is Everything!

Reviewed January 2025


Meticulous, scrupulous and passionate are terms that describe the fervor, zeal and seriousness displayed by the kosher consumer regarding Pesach kashrus in general, and Pesach matzos in particular.  The kosher consumer has become more sophisticated and savvy with each passing year. Kosher consumers are willing to pay top dollar for a quality kosher product. Pesach matzohs are no exception. Machine matzos with fine mehadrin hechsherim are readily available on the supermarket shelf.  Are all machine matzos created equal?

Regarding matzah baking and the time parameters for chimutz, leavening, the Shulchan Aruch1states, “One should not leave the dough dormant, not for a moment.” If the dough is constantly being worked the chimutz process is impeded.However, the Shulchan Aruch continues, “If the dough is left dormant for a ‘mil’, the dough […]

The Rise of Oat Matzos

The advent of baking oat matzah for Pesach is a relatively new phenomenon. As one of the Five Grains, oats qualify as an ingredient for matzah. Until circa 5740 (1980s), however, it never appeared in recorded halacha as something that was done in actual practice.

If someone with a wheat allergy can tolerate spelt, matzah made from spelt is an ideal alternative. Spelt and wheat are closely related both structurally and halachically. Additionally, some suggest that the order of grains in the Mishnah has significance. Thus, spelt, which appears third in the list, takes precedence over rye or oats. Others reject this notion and hold that position on the list does not indicate hierarchy for matzah.

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 […]
