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

What each ingredient does

Butter
Carries flavour from the vegetables and adds richness to the sauce.
Flour
Thickens the sauce by forming a roux with the butter that binds to the liquid.
Chicken or veal stock
Forms the main liquid and adds savoury depth to the sauce.
Cream
Adds body and a smooth, silky texture to the finished sauce.
Onion
Provides aromatic sweetness as it cooks in the butter.
Carrot
Adds subtle sweetness and aroma to the flavour base.

The step that matters

Gradually add the stock and cream, stirring continuously. Adding liquid slowly while stirring lets the flour starch disperse evenly and hydrate, which prevents lumps and gives a smooth, evenly thickened sauce.
