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

What each ingredient does

Horseradish
Supplies the sharp, pungent flavour that infuses into the vinegar.
Vinegar
Extracts horseradish's volatile compounds and carries its flavour as the acidic base.

The step that matters

Covering the jar tightly while it steeps. Horseradish's pungent compounds are volatile and escape easily, so a tight cover keeps the aroma in the vinegar and makes the flavour stronger.

Swap the shallot

The recipe marks shallot as optional. How well each one fits the dish's main ingredients (horseradish, vinegar):

  1. Mustardfits better
  2. Radishfits better
  3. Beetrootfits about as well
  4. Shallotthe original

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