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

What each ingredient does

Milk
Forms the liquid base that the flour thickens into a smooth sauce.
Flour
Starch that swells when heated in liquid, thickening the milk.
Egg white
Whipped to a froth, it adds lightness and airy texture to the thickened milk.

The step that matters

Cook the flour mixture thoroughly. Flour starch must be heated long enough in the milk to swell and thicken fully. If undercooked, the mixture stays thin and may taste of raw flour.
