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

What each ingredient does

Horseradish (in the method)
Provides the sharp, pungent heat that defines the sauce.
Cider vinegar
Adds acidity that sharpens the flavor and balances the sweetness.
Egg
Beaten in to add body and a richer, smoother texture.
Cream
Adds moisture and richness, mellowing the horseradish bite.
Butter
Adds fat and a smooth, rounded mouthfeel.

The step that matters

Adding the egg and cream just before serving. Horseradish loses its pungency and the sauce can thin or separate if it sits too long after the cream is added, so the cream should be beaten in right before serving.

Swap the radish

How well each one fits the dish's main ingredients (horse, egg, cider, vinegar, butter, cream, sugar):

  1. Mustardfits better
  2. Radishthe original
  3. Cucumberfits about as well
  4. Capsicumfits less well

Fit is the average pairing score against horse, egg, cider, vinegar, butter, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
