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 form the relish base.
- Apples
- Add tartness and pectin that help the relish thicken as it cooks.
- Onions
- Contribute savory depth and soften into the body of the relish.
- Vinegar
- Adds acidity that gives the relish its sharp flavor and aids preservation.
- Sugar
- Balances the acidity and, with long cooking, helps thicken the relish.
The step that matters
Continue boiling until the mixture thickens. Relish thickens only as liquid evaporates during long simmering. Stopping early leaves it thin and watery, and it may spoil sooner in storage.
