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

What each ingredient does

Horseradish
Provides the sharp, pungent heat that defines the sauce.
White sauce
Forms the creamy base that carries the other flavours and gives body.
Bread crumbs
Thicken the sauce and add body as they absorb liquid.
Vinegar
Adds acidity that brightens the sharp horseradish flavour.
French mustard
Adds sharpness and depth that complements the horseradish.

The step that matters

Heating over hot water. Gentle heat over hot water warms the sauce without boiling it. Overheating can cause a cream or egg-based sauce to separate or curdle, and it can dull the horseradish's pungency.

Swap the horseradish

How well each one fits the dish's main ingredients (bread, vinegar, sugar, sauce, mustard, pepper):

  2. Capsicumfits about as well
  3. Shallotfits about as well
  4. Lettucefits less well

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