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 pickle and give it a crisp bite once drained.
- Onions
- Add sharp, savoury flavour that mellows during the long steep in vinegar.
- Coarse sea salt
- Draws water out of the cucumbers and onions so the pickle stays firmer.
- Mustard seed
- Adds a sharp, pungent flavour that carries through the pickle.
- Celery seed
- Contributes a warm, aromatic celery flavour.
- Cider vinegar
- Provides acidity that gives the pickle its tang and helps preserve it.
The step that matters
Draining overnight with salt. Salt pulls water out of the chopped cucumbers and onions through osmosis. Draining long enough removes that water, so the pickle stays crisp rather than watery once covered with vinegar.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, mustard, pepper, celery, cider, vinegar):
- Horseradishfits better
- Lettucefits better
- Radishfits better
- Onionthe original
Fit is the average pairing score against cucumber, mustard, pepper, celery, cider, vinegar. Candidates are from the same food group and used in at least 100 recipes.
