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

What each ingredient does

Horse-radish
Supplies the pungent flavour that the vinegar draws out and carries.
Sugar
Balances the sharpness of the vinegar with a touch of sweetness.
Wine or cider vinegar
Extracts the horseradish's heat and acts as the preserving liquid.

The step that matters

Covering the jar tightly during the ten-day steep. Horseradish's pungent aroma is volatile and dissipates when exposed to air. A tight cover keeps the flavour compounds in the vinegar, so the infusion stays strong and aromatic.

Swap the radish

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

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

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