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

What each ingredient does

Butter
Enriches the sauce with fat, giving it a smooth, rich mouthfeel.
Flour
Thickens the sauce as its starch swells in the warm liquid.
Water
Forms the liquid base that the butter and flour thicken into a sauce.

The step that matters

Stir over low heat without boiling. Flour thickens best when the starch swells gently in warm liquid. Boiling can cause the sauce to become lumpy or break, so low heat and steady stirring keep it smooth.
