Matzah balls
Matzah balls (also matza balls, matzo balls, or matzoh balls) are a traditional Jewish food made from matzah, the unleavened bread used during the Passover holiday. Matzah balls are roughly spherical and range from fluffy to dense and doughy in texture; they can be anywhere from a few centimeters in diameter to the size of a large orange. They are most commonly served in chicken broth or soup as "matzah ball soup," a dish that is somewhat akin to a soup or thin stew with dumplings.
Matzah balls are a very common Passover food among Ashkenazic Jews and are sometimes eaten at other times of year; Sephardic Jewish customs often vary.
