Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce with starch and, when browned with butter, adds a nutty flavor.
- Butter
- Carries the flour and adds richness and flavor to the sauce base.
- Beef stock
- Provides the liquid base and savory flavor of the sauce.
- Heavy cream
- Adds fat for a smooth, rich texture and a creamy finish.
The step that matters
Whisking the flour into the browning butter. Flour must be cooked in the fat until it is evenly mixed and lightly browned; stirring it in cleanly prevents lumps and removes raw starch taste. Scorching the butter gives a bitter flavor, so watch the color closely.
