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

What each ingredient does

Cucumbers
Form the main bulk of the pickles, providing crisp texture once sliced thin.
Onions
Add savory sweetness and aroma as they soften in the salt-drawn brine.
White mustard seed
Provides sharp, pungent flavour that mellows during pickling.
Olive oil
Adds fat, richness and a fruity flavour to the pickle mixture.

The step that matters

Drain off all water after standing overnight. Salt draws water out of the cucumbers and onions. Draining it fully removes this liquid, so the pickles stay crisp and the vinegar and oil are not diluted.

Swap the onion

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

  1. Lettucefits better
  2. Horseradishfits better
  3. Broccolifits better
  4. Onionthe original

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