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.
Apples
Cooked and grated to add body and mellow sweetness that softens the horseradish bite.
Vinegar
Adds acidity that sharpens flavour and helps keep the sauce bright.

The step that matters

Grating the horseradish. Cutting or grating horseradish releases volatile compounds that create its heat, and these fade quickly once exposed to air. Working promptly and keeping the sauce covered helps preserve pungency. Cooled apples keep the paste thick rather than watery.

Swap the horseradish

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

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

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