Bisque
From Cookipedia
Bisque is a thick, creamy, highly-seasoned soup of French origin, classically of puréed crustaceans. It can be made from lobster, crab, shrimp or crayfish. Also, creamy soups made from vegetables instead of seafood are sometimes called bisques.
High quality bisques make a very good stock base for fish dishes such as Salmon and prawn tagliatelle, Spicy prawn ravioli etc.
