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

What each ingredient does

Madeira wine: Adds depth and a subtly sweet, rich flavour to the sauce as it reduces.
Sauce tournée: Provides body and a thickened, velvety texture to the sauce.
Chopped mushrooms: Contribute savoury, earthy flavour and moisture to the sauce.

Fit is the average pairing score against madeira wine, sauce, mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
