Chowder is a type of soup or stew often prepared with milk or cream and thickened with broken crackers, crushed ship biscuit, or a roux. Variations of chowder can be seafood or vegetable. Crackers such as oyster crackers or saltines may accompany chowders as a side item, and cracker pieces may be dropped atop the dish. New England clam chowder is typically made with chopped clams and diced potatoes, in a mixed cream and milk base, often with a small amount of butter. Other common chowders include seafood chowder, which includes fish, clams, and many other types of shellfish; lamb or veal chowder made with barley; corn chowder, which uses corn instead of clams; a wide variety of fish chowders; and potato chowder, which is often made with cheese. Fish chowder, corn chowder, lamb chowder and especially clam chowder are popular in the North American regions of New England and Atlantic Canada; and internationally in New Zealand.
