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

What each ingredient does

Butter
Adds richness and a smooth, creamy body to the sauce.
Sugar
Creams with the butter and adds gentle sweetness.
Flour
Thickens the hot milk so the sauce coats a spoon.
Milk
Forms the liquid base that the flour thickens into sauce.

The step that matters

Stirring in the butter and sugar off the heat. Adding the creamed mixture quickly and away from direct heat keeps it blending smoothly into the thickened milk instead of melting unevenly or separating. Stirring steadily prevents lumps and keeps the sauce light and even.
