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

What each ingredient does

Mushrooms
Provide the main flavour and body of the sauce.
Butter
Carries flavour and enriches the sauce while the stems cook.
Flour
Thickens the brown stock into a smooth sauce.
Brown stock
Forms the liquid base that the flour thickens.
Truffle
Adds a concentrated earthy aroma at the end.

The step that matters

Add flour and gradually pour in the brown stock. Adding the liquid gradually while the flour is in the pan lets the starch disperse evenly, which prevents lumps and gives a smooth, thick sauce.
