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):
- Lettucefits better
- Horseradishfits better
- Broccolifits better
- 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.
