Chowders tend to be more stew-like or chunky, and bisques puréed. Bisques are traditionally made with shellfish, though these days a puréed tomato, cream-based soup can be called a bisque too. We half-puréed this smoked salmon bisque, which accounts for the photograph. My father made this delicious soup the other day after being inspired by a bisque we had at a local bistro and wine bar. So creamy and good! Garnish with fresh dill.
