Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Truffles
- Provide the main flavor and are the featured element of the sauce.
- Good gravy
- Forms the liquid base of the sauce and carries the savory flavor.
- Flour
- Thickens the gravy into a smooth, lightly body sauce when cooked with butter.
- Butter
- Enriches the sauce with fat and adds a rounder, silkier mouthfeel.
- White wine
- Adds acidity that brightens the gravy and balances its richness.
The step that matters
Stew gently until the truffles are tender. High heat can toughen the truffles and drive off their delicate aroma. A gentle simmer softens them while keeping their flavor intact.
