Clam chowder is any of several chowders containing clams and broth. Along with the clams, potato chunks are common, as are onions, which are occasionally sauteed in the drippings from salt pork. Other vegetables are uncommon, but small carrot strips might occasionally be added, primarily for color. A garnish of parsley serves the same purpose. Bay leaves are also sometimes used as a garnish and flavoring.
