Matzo must be ground from one of the five grains specified in Jewish law for Passover matzo: wheat, barley, spelt, rye or oat. Per Ashkenazic tradition, matzo made with wine, fruit juice, onion, garlic, etc., is not acceptable for use at any time during the Passover festival except by the elderly or unwell. Matzo dough is quickly mixed and rolled out without an autolyse step as used for leavened breads. Most forms are pricked with a fork or a similar tool to keep the finished product from puffing up, and the resulting flat piece of dough is cooked at high temperature
Matzo Whole wheat, bran and organic matzo are also available. Chocolate-covered matzo is a favorite among children, although some consider it "enriched matzo" and will not eat it during the Passover holiday. A quite different flat confection of chocolate and nuts that resembles matzo is sometimes called "chocolate matzo". Matzo contains typically 111 calories per 1-ounce/28g (USDA Nutrient Database), about the same as rye crispbread. "Shĕmura" ("guarded") matzo ( "matsa shĕmura") is made from grain that has been under special supervision from the time it was harvested to ensure that no fermentation has occurred, and that it is suitable for eating
