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

What each ingredient does

Butter
Adds fat and richness, carrying flavour through the sauce.
Flour
Thickens the sauce as its starch swells when cooked with the melted butter and liquid.

The step that matters

Gradually add the water and seasoning. Adding liquid slowly to the hot butter and flour mixture lets the starch disperse evenly, which prevents lumps and gives a smooth sauce.
