Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White wine
- Adds acidity and aroma as it reduces, building the sauce's base flavour.
- Veal gravy
- Provides the savoury body and depth that the reduced liquid carries.
- Butter
- Enriches the sauce, giving it a glossy texture and rounder mouthfeel when melted in.
- Mushroom trimmings
- Contribute earthy, savoury flavour during the reduction.
The step that matters
Reducing the wine and gravy. Reducing concentrates flavour and thickens the liquid by evaporating water. Stopping too early leaves the sauce thin and weak, while over-reducing makes it too salty or intense.
Swap the tarragon
