“Kosher” is an adjective (“kashrut” is the noun) used to describe food that is “fit” or “clean” or, in other words, prepared and served according to Judaism’s 3,000-year-old dietary laws.
In general, kashrut prohibits the eating of pork (Muslims proscribe pork too) and shellfish, or the mixing of meat ingredients with dairy ingredients. (It’s more complicated than that, but these are the basic nuts and bolts.)
Many Israelis observe kashrut – or some version of it – while many, perhaps most, do not. Almost every hotel in Israel is kosher (so that anyone can eat or stay there), but the majority of Israeli restaurants are not kosher. Restaurants that are kosher display a kashrut certificate; kosher restaurants usually close after lunch on Friday and don’t reopen until late Saturday night, or noon on Sunday.Back
