Why it works: Cider and vinegar are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the bulk of the relish and supply its fresh, crisp texture.
- Onions
- Add savory pungency and aroma that balances the sweetness and acidity.
- Cider vinegar
- Provides acidity that preserves the relish and gives it a tangy flavor.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
The step that matters
Boil just long enough. Overboiling softens the cucumbers and dulls their fresh crunch, while boiling too briefly may not safely preserve the relish. The goal is enough heat to preserve without losing texture.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, cider, vinegar, pepper, sugar):
- Mustardfits better
- Capsicumfits better
- Radishfits better
- Onionthe original
Fit is the average pairing score against cucumber, cider, vinegar, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
