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

What each ingredient does

Butter
Adds richness and flavour, and forms the fat base that the flour thickens.
Flour
Thickens the sauce by absorbing liquid as it cooks with the butter and milk.
Milk
Forms the liquid body of the sauce, which thickens as the starch swells.

The step that matters

Adding the milk gradually while stirring. Pouring in the milk slowly and stirring constantly keeps the flour and butter mixture smooth. Adding liquid too fast or without stirring lets lumps form as starch clumps before it can disperse evenly.
