Dumplings are cooked balls of dough. They are based on flour, potatoes or bread, and may include meat, fish, vegetables, or sweets. They may be cooked by boiling, steaming, simmering, frying, or baking. They may have a filling, or there may be other ingredients mixed into the dough. Dumplings may be sweet or spicy. They can be eaten by themselves, in soups or stews, with gravy, or in any other way. While some dumplings resemble solid water boiled doughs, such as gnocchi, others such as wontons resemble meatballs with a thin dough covering.
