Matzo meal is unleavened bread that has been ground into fine crumbs that resemble cornmeal. It's unleavened because it's made without yeast or any type of raising agent. Matzo meal is used as a binder to help food retain its shape, or to coat food for frying or baking. Since it's made from wheat, using matzo meal does not make your latkes gluten-free or keto friendly. You would have to leave it out completely if you're following a special diet.
