Matzo (also spelled matzoh or matza) is crisp dried bread with no leavening agent.

A traditional Jewish food, it can be eaten all year round. It's particularly important to the Passover holiday. Matzo supposedly originated because the Jewish slaves didn’t have time to allow their bread to rise before fleeing Egypt; they baked it flat to take with them.

Matzo usually comes in large sheets, but is also made into smaller crackers and ground up into meal, to use as breading or make into matzo balls for soup.
