Why it works: Tomato and cucumber are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 2,405 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Provides bulk and a firm, crisp texture that holds up during long simmering.
- Cucumbers
- Supply crunch and water that the salt draws out during the overnight rest.
- Coarse sea salt
- Draws moisture out of the vegetables, firming them and helping preserve the relish.
- Vinegar
- Provides acidity that preserves the relish and gives it its tangy flavor.
- Brown sugar
- Adds sweetness that balances the sharp vinegar and browns slightly during cooking.
The step that matters
Draining the brine before adding spices and vinegar. Salt has drawn a lot of liquid from the vegetables overnight. Draining it off keeps the relish from becoming overly salty and helps it cook into a thicker, more concentrated texture rather than a watery one.
Swap the onion
