  3. In the same liquor, add the milk or cream, cold butter, cayenne pepper, and salt.

  4. Thicken the mixture with flour stirred into a paste.

  5. Bring to a boil, then add the oysters back into the sauce.

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 texture, and release their liquor to season the sauce.
Milk or cream
Adds richness and body, mellowing the sauce into a smooth, creamy base.
Cold butter
Adds fat for silky richness and helps give the sauce a glossy finish.
Flour
Thickens the liquid as it heats, giving the sauce a smooth, cohesive body.

The step that matters

Thicken with flour paste before boiling. Flour must be stirred into a smooth paste first so it disperses without lumps. Starch thickens the sauce as it heats, so the mixture needs to reach a boil to fully set.
