from bread, cakes and other foods made with yeast and leavening agents. In modern times, rabbinical authorities permit the use of chemical leavening, such as baking powder. Matza is a staple food during the holiday and used as an ingredient of many Passover dishes. Kneidlach (matza ball) soup is traditional. Fish is coated with matza meal before frying and cakes and puddings are made with potato starch and matza meal. Jewish cooks use both matza meal and potato starch for pastries during Passover. Whisked whole eggs or egg whites are frequently used to make pastries without leavening agents, such as angel and sponge cakes (potato starch replacing cake flour) and coconut and almond macaroons. Passover foods vary distinctly between Sephardic and Ashkenazic communities. Ashkenazim exclude rice, while it is served by Sephardim. Matza is traditionally prepared from water and flour only, but there are other varieties, such as egg matza, which may also contain fruit juice. At the seder, it is customary in some communities, particularly among strictly Orthodox Jews, to use handmade , which has undergone particularly strict kashrut supervision. The exclusion of leaven from the home has forced Jewish cooks to be creative, producing a wide variety of Passover dishes that use matza meal and potato as thickeners. Potato flour is largely used in cakes along with finely ground matza meal and nuts. Popular Ashkenazi dishes are matza brei (crumbled matza with grated onion, fried with scrambled egg), matza latkes (pancakes) and chremslach (also called crimsel or gresjelies, matza meal fritters). Wined matza kugels (pudding) have been introduced into modern Jewish cooking. For thickening soups and sauces at Passover fine matza meal or potato flour is used instead of flour, for frying fish or cutlets a coating of matza meal and egg, and for stuffing potatoes instead of soaked bread. "Noodles" may be made by making pancakes with beaten eggs and matza meal which, when cooked, are rolled up and cut into strips. They may be dropped into soup before serving. (dumplings) are small balls made from suet mixed with chopped fried onions, chopped parsley, beaten egg and seasonings, dropped into soup and cooked. Wine is also an important part of Passover meals. Traditionally, a Passover seder is served with four cups of wine or grape juice, to be consumed along with various parts of the seder. Kosher wine is typically consumed for Passover.
