Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Ripe tomatoes
Provide the bulk and fresh, juicy body of the relish.
Celery
Adds crisp texture and a mild, fresh vegetable flavor.
Small onion
Adds sharp, savory aroma that balances the sweetness.
Sugar
Adds sweetness that rounds out the acidity of the vinegar.
Vinegar
Adds acidity that brightens the flavor and helps preserve freshness.

The step that matters

Stir in sugar and vinegar to taste. Sugar and vinegar balance each other, and the acidity of vinegar sharpens flavors. Adding them gradually and tasting as you go keeps the relish from becoming too sweet or too sour.

Swap the onion
