Cajuns love their seafood. This “soup for the Cajun soul” can be made with crab, shrimp, crawfish, all three or in combination with each other. Most everyone use the term Bisque and Chowder interchangeably. However bisque is smooth, chowder is thick and chunky. Traditionally it's pieces of vegetables and seafood. It also usually includes milk, half-half or cream, and gets some of its thickness from hearty vegetables, like potatoes.
