What does Bisque refer to in terms of soup?

Bisque specifically refers to a type of soup that is traditionally made from shellfish, such as lobster, crab, or shrimp. The hallmark of a bisque is its rich creaminess and depth of flavor, which comes from the shells of the shellfish that are roasted and then simmered to extract their essence. This process often includes the addition of aromatics and cream, resulting in a luxurious, velvety texture that distinguishes bisques from other soups.

The choice of shellfish as the primary ingredient in bisques highlights the elevated technique and flavor profile associated with this dish, making it a classic preparation in French cuisine. Other types of soups, such as vegetable broths or clear stocks, do not embody the specific characteristics or preparation methods associated with bisque. Thus, the precise definition of bisque is firmly rooted in its identity as a shellfish soup, making it distinct from other soup variations.
