Pictured above: Box of Matzo crackers. Matza (also Matzah, Matzoh, or Matsah) is a cracker-like unleavened bread made of white plain flour and water. It is similar in preparation to the Southwest Asian lavash and the Indian chapati. Matza is also the substitute for bread during the Jewish holiday of Passover, when eating chametz—bread and leavened products—is not allowed. [Source: Wiki] QUICK FACT: My mother is a matzo cracker addict and definitely recognizes this box.
