Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Provide the crisp, bulky body of the relish, which salting firms up.
Onions
Add sharp flavour and bulk that softens slightly in the brine.
Coarse sea salt
Draws water out of the cucumbers and onions, concentrating flavour and firming the texture.
Vinegar
Adds acidity that gives the relish its tang and helps preserve it.

The step that matters

Salting overnight. Salt draws water out of the cucumbers and onions by osmosis. Draining them well afterwards keeps the relish crisp rather than watery, and the vegetables must be rinsed so the relish is not overly salty.

Swap the clove

How well each one fits the dish's main ingredients (cucumber, onion, celery, vinegar):

  1. Tarragonfits better
  2. Garlicfits better
  3. Dillfits better
  4. Clovethe original

Fit is the average pairing score against cucumber, onion, celery, vinegar. Candidates are from the same food group and used in at least 100 recipes.
