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

What each ingredient does

Oysters: Provide the main flavour and tender texture of the sauce.
Butter: Adds richness and fat, giving the sauce a smooth, silky mouthfeel.
Flour or arrowroot: Thickens the melted butter and liquid so the sauce becomes smooth and lightly bodied.
Milk: Adds moisture and mild sweetness, softening the sauce's flavour.

The step that matters

Simmer gently without boiling. Boiling toughens oysters and can cause the sauce to separate or curdle, so keep the heat low and steady.

Fit is the average pairing score against oyster, butter, pepper, flour, milk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
