Gyoza are Japanese dumplings that are typically filled with ground meat and vegetables, often seasoned with garlic and ginger. They are usually made with a thin dough wrapper and can be cooked in various ways, including pan-frying, steaming, or boiling. Gyoza are commonly served with a dipping sauce made from soy sauce, vinegar, and chili oil. Originally derived from Chinese jiaozi, gyoza became popular in Japan after World War II. They are often enjoyed as an appetizer or side dish and are a staple in many Japanese restaurants. Gyoza can also be found in frozen form for easy preparation at home.
