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

What each ingredient does

Boiled and smoked tongue
Provides the meaty bulk and savory flavor that forms the body of the spread.
Butter
Adds fat and richness, giving the spread a smooth, spreadable texture.
Truffles
Contribute an earthy, aromatic flavor to the spread.
Estrogan vinegar
Adds acidity that brightens the rich fat and meat flavors.
French mustard
Adds sharp, pungent flavor that cuts through the richness of the butter.

The step that matters

Pound the mixture until perfectly smooth. Pounding breaks the meat fibers and fully emulsifies the butter with the other ingredients, so the spread holds together and spreads evenly rather than being grainy or separated.

Swap the mustard

How well each one fits the dish's main ingredients (truffle, butter, vinegar, pepper):

  1. Capsicumfits better
  2. Shallotfits about as well
  3. Asparagusfits about as well
  4. Mustardthe original

Fit is the average pairing score against truffle, butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
