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):
- Garlicfits better
- Tarragonfits better
- Thymefits better
- 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.
