Ingredients
Directions
Prepare
Slice green tomatoes and peppers, sprinkle with coarse sea salt, and let stand overnight.
Make the pickle
In a pot, combine vinegar, sugar, whole cloves, mustard seed, and celery seed; boil well.
Squeeze tomatoes to remove excess salt water, then add them to the boiling vinegar mixture.
Boil for 1 hour, then bottle the mixture while hot.

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 as they cook in the vinegar.
- Vinegar
- Provides the acidity that preserves the pickle and gives it its sharp flavour.
- Sugar
- Balances the vinegar's sharpness with sweetness.
- Coarse sea salt
- Draws water out of the tomatoes and peppers, firming them before pickling.
The step that matters
Squeeze tomatoes to remove excess salt water. Salt draws moisture out of the tomatoes. If too much brine stays with them, it dilutes the vinegar mixture and weakens its acidity, which can reduce how well the pickle keeps.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, vinegar, sugar, clove, mustard, celery):
- Horseradishfits better
- Capsicumfits better
- Lettucefits better
- Tomatothe original
Fit is the average pairing score against pepper, vinegar, sugar, clove, mustard, celery. Candidates are from the same food group and used in at least 100 recipes.
