Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lobster
Provides the main shellfish flavor and body, especially when the shells are pounded and cooked into the broth.
Rice
Thickens the broth as it cooks and softens, giving the bisque a smoother body.
Cream
Adds richness and a smooth, velvety texture to the finished bisque.
Tomatoes
Adds acidity and color, balancing the sweetness of the shellfish and vegetables.
Butter
Carries fat-soluble flavors from the shells and vegetables into the soup and adds richness.
Onion
Builds a sweet, savory base of flavor when softened in butter at the start.

The step that matters

Pounding the cooked lobster mixture to a paste. Crushing the shells and softened vegetables breaks them down so their flavor and color release into the broth during the long simmer. Pieces left whole would yield a thinner, less flavorful bisque.
