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):

  1. Mustardfits better
  2. Capsicumfits better
  3. Radishfits better
  4. 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.
