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.
