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

What each ingredient does

Stale bread
Provides the base structure that holds the sauce and toasts to a crisp, golden surface.
Milk
Forms the liquid base of the sauce, supplying moisture and creamy body.
Butter
Adds richness and fat, giving the sauce a smooth mouthfeel and flavor.
Flour
Thickens the hot milk mixture as its starch swells, giving the sauce body.

The step that matters

Adding the flour mixture to the hot milk. Flour must be fully smoothed in cold milk first, then stirred into hot liquid and cooked. Starch granules swell and thicken the sauce, while dumping dry flour in causes lumps.
