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 cooked into, adding richness and flavour.
Flour
Thickens the liquid as its starch swells and sets when cooked with the butter and boiled.
Milk and cream
Provides the main liquid and creamy body that gives the sauce its smooth, rich texture.
White stock or fish stock
Adds savoury depth and body to the liquid, suiting the sauce to poultry or fish.

The step that matters

Gradually add the milk and stock, stirring continuously until boiling. Adding the liquid slowly while stirring keeps the flour evenly dispersed, so lumps do not form. The starch thickens as the sauce comes to the boil, giving a smooth, cohesive sauce.

Swap the lemon
