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

What each ingredient does

Green tomatoes
Form the bulk of the pickle and soften into a tender, chunky texture when cooked.
Coarse sea salt
Draws water out of the vegetables overnight, firming them and helping preserve them.
Vinegar
Covers the vegetables and provides the sharp acidity that preserves and flavors the pickle.
Sugar
Balances the sharpness of the vinegar and adds sweetness to the pickle.
Grated horseradish
Adds pungent heat that mellows during cooking and cuts through the sweetness.

The step that matters

Pour off the water after salting overnight. Salt draws a lot of liquid out of the vegetables. If the liquid is not drained, the pickle will be watery and diluted, and the vinegar flavor will be weaker.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper, vinegar, horseradish, clove, cinnamon, allspice):

  1. Mustardfits better
  2. Capsicumfits better
  3. Cucumberfits better
  4. Onionthe original

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