Gizzards are a type of muscular stomach found in birds, including chickens and turkeys. They help grind up food, as birds do not have teeth. Gizzards are often considered a delicacy in various cuisines and are rich in protein and essential nutrients. In cooking, gizzards can be prepared in several ways, such as frying, boiling, or adding them to soups and stews. They are commonly used in dishes like gumbo and stuffing. Gizzards are typically sold alongside other poultry parts, such as livers and hearts, in grocery stores.
