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 matzo made from flour and water. The flour may be whole grain or refined grain, but must be either wheat, spelt, barley, rye, or oat. Some Sephardic communities allow matzos containing eggs and fruit juice to be used throughout the holiday. Passover and non-Passover matzo may be soft or crisp, but only the crisp "cracker" type is available commercially in most locations. Soft matzo, if it were commercially available, would essentially be a kosher flour tortilla. Non-Passover matzo may be made with onion, garlic, poppy seed, etc. It can even be made from rice, maize, buckwheat and other non-traditional flours
