Unleavened breads, such as the tortilla and roti, are staple foods in Central America and South Asia, respectively. Unleavened breads have symbolic importance in Judaism and Christianity. Jews consume unleavened breads such as matzo during Passover - various traditions explain this usage. Unleavened bread also features in some Western Christian liturgies during the Eucharist, a rite derived from the Last Supper when Jesus broke bread,
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
