Matzah
Matzah, also spelled matzo or matzoh, is an unleavened flatbread prepared from flour and water without any leavening agents, central to Jewish observance of Passover.[1][2] It is consumed during the holiday to commemorate the Israelites' rapid exodus from Egypt, as described in the Book of Exodus, when their dough could not rise due to the urgency of departure.[3][4] The bread symbolizes both the affliction of slavery, resembling the simple provisions of bondage, and the haste of liberation.[5] In Jewish tradition, matzah must be produced under strict conditions to ensure it remains kosher for Passover, using one of five grains—wheat, barley, spelt, rye, or oats—and baked within 18 minutes from the moment water contacts the flour to prevent natural fermentation into chametz.[6][7] This process involves constant kneading, rolling, perforating to inhibit air pockets, and rapid baking, traditionally done by hand for shmurah matzah, which is overseen from harvesting to baking, or by machine for mass production while adhering to the time limit.[8][9] During the Passover seder, matzah holds ritual prominence, broken and distributed as the bread of affliction and redemption, forming part of the core symbolic elements alongside bitter herbs and the Passover offering in historical context.[10]
