Matzo major forms of matzo. In many western countries the most common form is the hard form of matzo which is cracker-like in appearance and taste and is used in all Ashkenazic and most Sephardic communities. Yemenites, and Iraqi Jews traditionally made a form of soft matzo which looks like Greek pita or like a tortilla. Soft matzo is made only by hand, and generally with "shmurah" flour. Flavored varieties of matzo are produced commercially, such as poppy seed- or onion-flavored. Oat and spelt matzo with kosher certification are produced. Oat matzo is generally suitable for those who cannot eat gluten.
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
