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

What each ingredient does

Butter
Adds fat and rich flavour, and combines with the flour to form a roux.
Flour
Thickens the sauce as its starch swells in the hot liquid.
Reduced stock
Provides the main liquid and concentrated savoury flavour.

The step that matters

Adding the stock slowly. Flour starch coated in butter can clump if liquid is poured in quickly. Stirring while adding the stock disperses the starch granules, so the sauce thickens smoothly as it heats.
