Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide moisture and acidity that give the relish its body and tang.
- Cabbage
- Adds bulk and a crisp, firm texture that holds up during long cooking.
- Salt
- Draws water out of the vegetables, which is then drained off to firm them.
- Brown sugar
- Adds sweetness that balances the vinegar and spices.
- Vinegar
- Provides acidity that preserves the mixture and sharpens its flavor.
- Cloves
- Adds warm, aromatic spice notes to the finished relish.
The step that matters
Draining the brine in the morning. Salt pulls water out of the vegetables overnight. Pouring off that liquid removes excess moisture, so the chow chow stays thick rather than watery after boiling.
