Cod chowder

Chowder is a thick soup prepared with milk or cream, a roux, and seafood or vegetables. Oyster crackers or saltines may accompany chowders as a side item, and cracker pieces may be dropped atop the dish. Clam chowder from New England 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 often consists of fish, clams, and other types of shellfish; lamb or veal chowder made with barley; corn chowder, which uses corn instead of clams; various fish chowders; and potato chowder, which is often made with cheese. Fish, corn, and clam chowders are popular in North America, especially Atlantic Canada and New England. The origin of the term chowder is obscure. One possible source is the French word chaudron, the French word for cauldron, the type of cooking or heating stove on which the first chowders were probably cooked. Chodier was also a name for a cooking pot in the Creole language of the French Caribbean islands. Additionally, a Portuguese, Brazilian, Galician and Basque fish and shellfish stew is known as caldeirada which appears to have a similar etymology. Another possible source of the word "chowder" could be the French dish called chaudrée , which is a thick fish soup from the coastal regions of Charente-Maritime and Vendée. Yet another etymology could be the Quebecois French word chaudière, which means "bucket".
