Dumplings are cooked balls of dough. They are based on flour, potatoes, bread or matzoh meal, and may include meat, fish, or sweets. They may be cooked by boiling, steaming, simmering, frying, or baking. Ingredients may be as a part of a filling, or mixed throughout the dumpling. Dumplings may be sweet, spicy or savoury. They may be eaten alone, in soup, with gravy, or in many other presentations.
