Type	Flatbread

Matzo, matza or matzah (Yiddish: מצה‎ matsah, Hebrew: מַצָּה‎ matsa; plural matzot; matzos of Ashkenazi Hebrew dialect) is an unleavened flatbread that is part of Jewish cuisine and forms an integral element of the Passover festival, during which chametz (leaven and five grains that, per Jewish Law, can be leavened) is forbidden.

Matzo that is kosher for Passover is limited in Ashkenazi tradition to plain 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. Sephardic tradition also allows eggs to be used.

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 that can never be used for Passover matzo. Gluten-free matzo-lookalike made from potato starch, tapioca, and other non-traditional flour is available and may be eaten on Passover, but does not fulfill the commandment of eating matzo, even for people with celiac disease who cannot eat Passover matzo, because matzo must be made from one of the five grains (wheat, barley, oat, spelt, and rye), all of which contain gluten, except for most (but not all) types of oat matzo. Oat matzo may only be used by those who cannot have any other kind because it's not certain that oat is actually one of the five grains (it may be a mistranslation), so those who can have wheat matzo should do so.
