Chowder is a thick, creamy soup that often includes ingredients like potatoes, onions, and celery. It is commonly made with seafood, such as clams or fish, but can also be prepared with vegetables or meats. The base is typically a mixture of milk or cream and broth, giving it a rich texture. There are many regional variations of chowder, with New England clam chowder being one of the most famous. This version is known for its creamy consistency and is often served with crackers. Other types include Manhattan clam chowder, which has a tomato base, and corn chowder, featuring sweet corn as the main ingredient.
