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

What each ingredient does

Truffles
Provide the main flavour and aroma of the sauce, and become the dish's centrepiece.
Good gravy
Forms the savoury liquid base that carries the sauce's body and flavour.
White wine
Adds acidity and brightness that balances the rich gravy and bacon fat.
Bacon fat
Contributes richness and savoury depth to the stewing liquid.
Flour and butter
Thicken the gravy into a smooth, cohesive sauce texture.

The step that matters

Stew gently until the truffles are tender. Gentle heat softens truffle flesh evenly without boiling it apart. Vigorous boiling can toughen or break the delicate pieces and cloud the sauce.

Swap the onion

How well each one fits the dish's main ingredients (truffle, white wine, parsley, thyme, flour, butter):

  1. Shallotfits better
  2. Leekfits better
  3. Chivefits better
  4. Onionthe original

Fit is the average pairing score against truffle, white wine, parsley, thyme, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
