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 relish and release their water when salted.
- Coarse sea salt
- Draws water out of the tomatoes so the relish stays firm rather than watery.
- Vinegar
- Adds sharp acidity that sets the flavor and helps keep the relish stable in jars.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Onions
- Contribute sharp aroma and savory flavor that deepens during cooking.
- Cucumbers
- Add crisp texture to the cooked relish.
The step that matters
Cook until clear. Cooking drives off excess water and softens the vegetables while the vinegar and sugar concentrate. Stopping too early leaves the relish watery, while overcooking turns the vegetables mushy.
Swap the onion
How well each one fits the dish's main ingredients (tomato, vinegar, sugar, cinnamon, cucumber, allspice, pepper):
- Capsicumfits better
- Mustardfits better
- Eggplantfits better
- Onionthe original
Fit is the average pairing score against tomato, vinegar, sugar, cinnamon, cucumber, allspice, pepper. Candidates are from the same food group and used in at least 100 recipes.
