Matzo, also spelled matzah and matzoh, is a type of unleavened flatbread traditionally eaten over Passover, when leavened breads are prohibited. It symbolizes The Israelites’ hasty escape from Egypt, where they didn’t have time to let their bread rise before going into the desert. Recipes like vegan matzo ball soup, matzo brei, and this morish matzo bark have become some of our Passover favorites.
