The primary ingredient in a traditional chowder is typically some type of seafood or a starch like potatoes. In New England clam chowder, for example, clams are the star ingredient, while in a corn chowder, fresh corn is used. Chowders are creamy and thickened soups often made with milk or cream, alongside other ingredients like vegetables and herbs. The creamy base allows the flavors to meld beautifully, making chowder a hearty and comforting dish. Variations can be found across different regions, each offering a unique twist depending on local ingredients and culinary traditions.
