Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the main body and bulk of the pickle, holding their shape while cooking.
- Onion
- Adds savory depth and aroma as it softens in the vinegar.
- Coarse sea salt
- Draws out juice from the tomatoes and onion, firming the pieces for pickling.
- Brown sugar
- Balances the sharpness of the vinegar with sweetness.
- Strong vinegar
- Acidifies the pickle, providing the sharp tang that preserves and flavors it.
The step that matters
Overnight salting and pressing out the juice. Salt draws water out of the tomato and onion pieces through osmosis. Pressing off this liquid keeps the pickle firm and stops excess water from diluting the vinegar, so the brine stays strong and the texture stays crisp rather than soggy.
Swap the tomato
How well each one fits the dish's main ingredients (onion, pepper, mustard, turmeric, sugar, vinegar):
- Horseradishfits better
- Shallotfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against onion, pepper, mustard, turmeric, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
