Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the bulk of the pickle and supply the body and moisture of the relish.
- Onions
- Add savory bulk and sharpness that mellows during the long slow stew.
- Vinegar
- Provides the acidity that preserves the pickle and sharpens its flavor.
- Sugar
- Balances the vinegar's sharpness and helps thicken the stewed mixture.
- Coarse sea salt
- Draws liquid out of the tomatoes and onions during the 24-hour standing step.
The step that matters
Stewing slowly after the salt rest. Salt has drawn out much of the tomato and onion liquid, so the mixture must simmer gently and long enough to reduce and thicken. Stirring in sugar near the end, rather than at the start, lets it dissolve without scorching in the thickening pan.

Fit is the average pairing score against tomato, vinegar, mustard, ginger, clove, allspice, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
