A knish is a food that consists of pastry wrapped around a filling of potato and onion. Knishes, which originated in Eastern Europe, may be baked or fried. The filling may also include meat, kasha, cheese or vegetables. The knish is an important part of the Jewish food tradition.
Knishes are key to many cultural traditions. Each group uses its own recipe, resulting in knishes of different sizes, shapes, cooking methods and filling. Homemade knishes are usually baked. At restaurants, chefs may prepare the foods in a deep fryer or on the grill. In New York, knishes were once a popular food at food carts and street stands.
