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

What each ingredient does

Oysters: Provide the main seafood flavor and tender texture in the stew.
Butter: Carries the aromatics and adds rich, savory fat to the stew.
White flour: Thickens the stew by absorbing liquid as it cooks with the milk and broth.
Whole milk: Forms the creamy body of the stew and adds sweetness and richness.
Oyster broth: Adds concentrated briny oyster flavor and liquid to the stew.
Celery: Adds a fresh, vegetal aroma that builds the stew's base flavor.

The step that matters

Add the oysters and broth, then remove from heat immediately. Oysters overcook quickly and turn rubbery when held at high heat, so they should be added and removed from the heat right away, letting residual heat cook them gently.
