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

What each ingredient does

Flour
Thickens the milk as the grated starch swells and sets into a smooth, creamy sauce.
Milk
Forms the liquid base that the flour thickens into a smooth, creamy sauce.

The step that matters

Stir the grated flour into the boiling milk until smooth. Starch grains clump if they hit hot liquid in a mass. Mixing the flour with the milk while stirring keeps the grains separated so they swell evenly and the sauce stays smooth rather than lumpy.
