The primary ingredient in a traditional New England clam chowder is clams, specifically quahog clams. This creamy soup is a hallmark of New England cuisine and is appreciated for its rich flavor and hearty texture. In addition to clams, the chowder typically includes ingredients such as potatoes, onions, celery, and heavy cream or milk, creating a thick, comforting dish. Some variations may incorporate bacon for added depth of flavor or seasonings like thyme and bay leaves. New England clam chowder is often enjoyed with oyster crackers on the side and is a popular dish in coastal areas of the northeastern United States.
