Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main savoury, briny flavour that defines the sauce.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Flour
- Thickens the sauce and gives it body as it heats.
The step that matters
Stir in the butter and flour until well combined. Flour clumps if it is added to hot liquid without thorough mixing. Stirring it in evenly and keeping the butter softened helps it disperse smoothly, so the sauce thickens without lumps.
