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

What each ingredient does

Butter
Melts to form the fat base that the flour is stirred into.
Flour
Thickens the liquid into a smooth sauce when cooked with the butter and water or milk.
Water or milk
Forms the liquid that the flour thickens into the sauce.

The step that matters

Stir in the flour and add the liquid gradually. Flour must be cooked briefly in the melted butter and whisked well into the liquid so starch granules swell evenly. Stirring until the mixture boils lets the starch thicken fully and prevents lumps.
