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

What each ingredient does

Mushrooms
Add earthy flavor and body to the sauce as they cook down.
Shallots
Add a mild onion-like sweetness and aroma as they soften in butter.
Butter
Carries the aromatics and adds richness to the sauce.
White wine
Adds acidity and depth, helping to build the sauce's flavor as it reduces.
Broth
Provides the liquid base that reduces into the body of the sauce.

The step that matters

Reduce the mixture to a proper thickness without skimming. Reducing concentrates flavor and thickens the liquid through evaporation. Skimming is not included in this method, so the cook must judge thickness by eye while the sauce reduces gently.

Swap the clove
