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 the vinegar draws out over the steeping time.
Strong vinegar
Acts as the solvent that extracts flavour from the horseradish and peppers and gives the sour bite.
Black pepper
Adds a warm, sharp aroma and background heat to the infused vinegar.
Cayenne pepper
Contributes direct chilli heat that builds in the vinegar as it steeps.

The step that matters

Pour the vinegar boiling hot over the dry ingredients. Heat helps the vinegar penetrate the plant material and pull out its volatile flavour compounds faster. Sealing the container while it steeps keeps those aromatic compounds from escaping, so the infusion stays strong.

Swap the horseradish

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

  1. Capsicumfits better
  2. Mustardfits better
  3. Cabbagefits better

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