Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and their own liquor, which becomes the base of the sauce.
- Butter
- Carries flavor and forms the fat base that is cooked with the flour.
- Flour
- Thickens the sauce when cooked with butter into a roux.
- Chicken stock
- Adds savory body and liquid to the sauce.
The step that matters
Stirring the butter and flour. If the flour is not stirred constantly and cooked for a few minutes, it stays raw-tasting and can form lumps, so the sauce will not be smooth.
