Clam chowder is any of the numerous clam-based chowder soups popular in American cuisine. In addition to clams, chopped potatoes, salt pork, and onions are frequent ingredients, and other vegetables are usually not used. Clams are thought to have been utilized in chowder because they are straightforward to gather. Saltine crackers or little hexagonal oyster crackers are commonly served with clam chowder.
The dish has its origins in the Northeastern United States, although it is now widely available in restaurants around the country.
