Unleavened Bread and Passover
Many traditional Jewish dishes come with exciting historical stories, and matzo is certainly no different. During the Exodus, the Jewish people were hurrying to get out of Egypt. They had been preparing bread before it began, and it was then baked without having time to rise. The result was matzo bread. Today, in celebration of Passover, which is also called Chag HaMatzot (the holiday of Matzot), it is customary to eat unleavened bread.Jewish News: Making matzo (April 22, 2005)
