Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk and liquid that forms the base of the relish.
- Green bell peppers
- Add crisp texture and a fresh, slightly bitter vegetal note.
- Onions
- Add savory depth and aroma as they soften during stewing.
- Vinegar
- Adds acidity that brightens flavor and helps preserve the relish.
- Sugar
- Balances the acidity of the vinegar and tomatoes with sweetness.
The step that matters
Stew until thickened. Stewing for the full 30 minutes to 1 hour, with occasional stirring, lets the tomatoes break down and water evaporate so the relish thickens and the spices blend. Stopping early leaves it thin and watery, and stirring prevents scorching on the bottom of the pot.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, vinegar, sugar, ginger, allspice, cinnamon):
- Capsicumfits better
- Mustardfits better

- Onionthe original
Fit is the average pairing score against tomato, pepper, vinegar, sugar, ginger, allspice, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
