Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Forms the bulk of the relish and softens into its thick body as it cooks.
- Onions
- Adds savory flavor and body, and softens into the relish during simmering.
- Sugar
- Adds sweetness that balances the vinegar and helps preserve the relish by binding water.
- Vinegar
- Adds acidity that sharpens the flavor and helps preserve the relish.
- Cloves
- Adds warm, aromatic spice flavor.
- Allspice
- Adds warm, aromatic spice flavor.
The step that matters
Boil gently, stirring frequently until tender. Sugar and cut vegetables can scorch on the bottom of the pan if left unattended. Gentle simmering with frequent stirring prevents burning and lets the tomatoes and onions soften evenly into a thick, uniform relish.
