Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 salty, briny character of the sauce.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- All-purpose flour
- Thickens the sauce as it boils, giving it body.
The step that matters
Boiling the sauce after adding the butter and flour. Flour only thickens fully when the mixture reaches a boil and is held there, so the sauce stays thin if it is not boiled long enough. Skimming foam first keeps the sauce clean and clear.
