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 form the body of the relish.
- Coarse sea salt
- Draws water out of the vegetables during the overnight soak, firming them and reducing excess liquid.
- Sugar
- Adds sweetness that balances the vinegar and spices.
- Vinegar
- Adds acidity that gives the relish its tang and helps preserve it.
- Horseradish
- Adds sharp, pungent heat that gives the relish its bite.
The step that matters
Cover with vinegar and boil until tender.. The vegetables must cook long enough to soften fully, but boiling too hard or too long can break them down into mush. Watching for tenderness rather than a set time helps keep the texture right.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, clove, allspice, cinnamon, sugar, horseradish):
- Mustardfits better

Fit is the average pairing score against tomato, pepper, clove, allspice, cinnamon, sugar, horseradish. Candidates are from the same food group and used in at least 100 recipes.
