Kashrut
Among the numerous laws that form "kashrut" are prohibitions on the consumption of certain animals (such as pork and shellfish), mixtures of meat and milk, and the commandment to slaughter mammals and birds according to a process known as "shechita". There are also laws regarding agricultural produce that might impact the suitability of food for consumption.
Israeli cuisine
Although not all Jews in Israel keep kosher, the tradition of "kashrut" strongly influences the availability of certain foods and their preparation in homes, public institutions and many restaurants, including the separation of milk and meat and avoiding the use of non-kosher foods, especially pork and shellfish. During Passover, bread and other leavened foods are prohibited to observant Jews and matza and leaven-free foods are substituted.
