Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide tart acidity and bulk that balances the sweetness of the sugar.
- Cabbage
- Adds crisp body and bulk that holds its texture through simmering.
- Sugar
- Adds sweetness and helps balance the sharpness of the vegetables and spices.
- Cucumbers
- Contribute moisture and a fresh crunch to the relish.
The step that matters
Simmering the mixture. Simmering for a long time lets the moisture from the vegetables release and evaporate while the flavors blend. Stirring keeps the bottom from scorching, and the relish thickens as the liquid reduces.
