Dumplings are a broad category of dishes consisting of pieces of dough, often wrapped around a filling. The image shows examples such as Jiaozi and Gyoza from East Asian cuisine, Momo and Samosa from South Asian cuisine, and Pierogi and Ravioli from European cuisine. The fillings and preparation methods (steamed, boiled, or fried) vary widely by region. A samosa, for example, is a fried pastry with a savory filling, while a ravioli is a pasta dumpling often filled with cheese or meat.
