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 release water when salted, leaving firmer pieces.
Coarse sea salt
Draws water out of the tomatoes, firming them and helping preserve the pickle.
Vinegar
Provides acidity that preserves the pickle and gives it its sharp flavour.
Whole cloves
Adds warm, aromatic spice flavour to the pickle.
Celery seed
Adds a savoury, earthy aroma that complements the tomatoes.
Small onions
Add sweetness and savoury flavour to the pickle.

The step that matters

Heating without boiling. Heating the mixture until it just scalds, without boiling, warms the vinegar enough to blend the spices while keeping the tomatoes firm. Boiling would soften them further and can drive off vinegar's acidity and aroma.

Swap the clove

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

  1. Garlicfits better
  2. Tarragonfits better
  3. Thymefits better
  4. Clovethe original

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