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
