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

What each ingredient does

Oysters: Form the main body of the dish, giving it its savory seafood flavor.
Butter: Carries the cooking of the shallot and pepper and enriches the sauce with fat.
Flour: Thickens the oyster liquor into a smooth sauce as it cooks.
Lemon juice: Adds acidity that brightens the rich sauce and balances its savoriness.
Beef extract: Adds concentrated savory depth to the sauce.

The step that matters

Add the oyster liquor gradually while stirring constantly. Pouring the liquid in slowly while stirring keeps the flour fully dispersed, so the sauce thickens smooth instead of forming lumps.
