Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg
Adds richness, body and a mild savory flavor to the sauce.
Flour
Thickens the sauce as its starch swells when heated with the liquid.
Butter
Adds fat for a smooth texture and rich flavor, and coats the flour.
Milk
Forms the liquid base that becomes the creamy body of the sauce.

The step that matters

Bring the mixture to a boil. Flour thickens only when its starch is heated in liquid until it swells. Mixing the flour and butter before adding the milk helps prevent lumps, and the sauce should be fully hot to reach full thickness.
