The classic New England Clam Chowder is traditionally made using hard-shell clams or quahogs, which are indigenous to the East coast. The clams are usually chopped or diced into small pieces and combined with potatoes, onions, celery, and a creamy broth to create the iconic soup. Other variations of seafood chowder may use different types of fish, shellfish, or crustaceans, depending on the region and local ingredients available. However, when it comes to New England Chowder, clams are undoubtedly the star of the show.
