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

What each ingredient does

Grated horseradish
Provides the sharp, pungent heat that defines the sauce.
Vinegar
Adds acidity that sharpens flavour and thins the paste into a smooth sauce.
Sugar
Adds a little sweetness that balances the sharpness of horseradish and vinegar.
Prepared mustard
Adds sharp, tangy flavour that complements the horseradish's bite.

The step that matters

To serve hot, heat the sauce in a bain-marie. Heat drives off the volatile compounds that give horseradish its pungency, so the sauce can lose its bite. Gentle, indirect heat in a bain-marie limits this loss and avoids scorching or curdling.

Swap the horseradish

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

  1. Horseradishthe original
  2. Capsicumfits about as well
  3. Radishfits less well
  4. Lettucefits less well

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