The Knead to Know: The Rise of Sourdough

By: Rabbi Tzvi Rosen

Fall 2023

We are all familiar with the Torah’s directive to rid our homes of chometz in order to prepare for Pesach. The Torah uses two terms when instructing us in the cleaning process: chometz and se’or.

Ask any talmid or talmida: “What is chometz,” and you will get a very erudite response. Ask the next question: “What is se’or,” and seven out of ten will shrug and say, “I dunno,” while the other three might venture, “Sourdough?” When you follow up and ask them to define sourdough, most – if not all – will say, “I dunno!”

Today, more and more homes are seeing sourdough boules find their way into their bread baskets. With its “rise” in popularity, it is only natural that we look into this new trend and ask, “Ma nishtana sourdough bread from its conventional counterpart? Are there halachic and practical differences?”

Click HERE for the Pesach 2024 Pet Food List.

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 […]

Halachos of Taking Medicine on Pesach

By: Rabbi Dovid Heber

Reviewed January 2024

For many years, Rav Gershon Bess prepared a Guide for Pesach Medications and Cosmetics which was published and distributed by Kollel Los Angeles. A partnership with STAR-K and the Kollel to make this information more widely available to the general public is still going strong after more than a quarter century. The Medications and Cosmetics Guide, available in Jewish bookstores nationwide, serves as an invaluable resource for kosher consumers seeking to purchase these items for Yom Tov.

Sefer Kovetz Halachos (Hilchos Pesach 12:4) states in the name of HaRav Shmuel Kamenetzky, shlit”a, that lechatchila one should take a medication approved for Pesach and mentions the availability and use of reliable Pesach lists and guides (see Hilchos Pesach, ibid., footnote 5).

The halachos pertaining to medication and cosmetic use on Pesach are based on the joint psak of Rabbi Moshe Heinemann, shlit”a, and Rav Gershon Bess, shlit”a.
