Which soup is known for containing clams?

Clam Chowder is specifically recognized for its primary ingredient—clams. This hearty, creamy soup is traditionally made by combining clams with ingredients such as potatoes, onions, and sometimes celery, resulting in distinctive, rich flavors that highlight the taste of the seafood. The lore and variations of clam chowder, particularly the New England style, emphasize the presence of clams as the defining characteristic. This experience distinguishes it from the other soups listed, which do not typically contain clams as a central ingredient. Tomato Soup, Red Bean Soup, and Baked Potato Soup focus on different flavors and components, lacking the unique feature that clam chowder offers.
