Matzah
Matzah, matzo, mazza, or maẓẓah (Hebrew: מַצָּה, romanized: maṣṣā; IPA: [maˈt͡sa], pl.: matzot or Ashk. matzos) is an unleavened flatbread that is part of Jewish cuisine and forms an integral element of the Passover festival, during which chametz (leavening agent and five grains deemed by halakha to be self-leavening) is forbidden.
