This week, during Shabbat morning worship, Jews around the world will read the foundational laws of kashrut (Jewish dietary law) from the Torah. These laws are extensive and specific because they describe the species of land, air, and sea animals that are kosher. In the thousands of years since this first iteration of kashrut, Jewish legal authorities have interpreted and expanded upon the original rules. Today, kashrut is a system of procedures for harvesting, preparing, and serving food, which people follow with varying levels of strictness.
