Margarine has a particular market value to those who observe the Jewish dietary laws of Kashrut, which forbids the mixing of meat and dairy products; hence there are strictly kosher non-dairy margarines available, known as Pareve. One brand known to the Kosher-keeping public is Fleischmann's Margarine. These are often used by the kosher-observant consumers to adapt recipes that use meat and butter or in baked goods served with meat meals. The 2008 Passover margarine shortage in America caused much consternation within the kosher-observant community.
