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

What each ingredient does

Shallots
Softened in butter, they add a mild, sweet aromatic base to the sauce.
Mushrooms
Release their savoury, earthy flavour into the sauce as they cook.
Brown stock
Forms the liquid body of the sauce and carries the other flavours.
White wine
Adds acidity and depth, and its flavour concentrates as the sauce boils.
Butter
Provides fat for frying the shallots and adds richness to the sauce.

The step that matters

Bring the sauce to a boil. Boiling reduces the liquid and concentrates the wine and stock flavours. Keeping the shallots soft before adding liquid prevents harsh, raw onion taste in the finished sauce.
