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 moisture that cook down into the relish body.
Vinegar
Adds acidity that gives the relish its sharp, tangy character and helps preserve it.
Sugar
Balances the acidity and sharpness with sweetness.
Onions
Add aromatic sweetness and savory depth as they soften during simmering.
Green peppers
Contribute fresh, slightly bitter vegetable flavor and body to the relish.

The step that matters

Long, gentle simmer. Simmering for 3 hours with occasional stirring lets water evaporate and the mixture thicken. Stirring prevents the sugar and tomato solids from scorching on the bottom of the pot.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper, sugar, vinegar):

  1. Capsicumfits better
  2. Cucumberfits better
  3. Mustardfits better
  4. Onionthe original

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