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 its crisp, fresh body.
- Coarse sea salt
- Draws water out of the vegetables, firming their texture and concentrating flavour.
- White mustard
- Adds sharp, pungent flavour that balances the sweetness of the onions and peppers.
- Cold vinegar
- Adds acidity that preserves the pickle and gives it its tangy taste.
The step that matters
Draining the salted mixture for 24 hours. Salt draws excess water out of the cucumbers, onions and peppers. Draining it fully keeps the pickle firm and stops extra liquid from diluting the vinegar in the jars.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, pepper, mustard, vinegar):
- Horseradishfits better
- Lettucefits better
- Radishfits better
- Onionthe original
Fit is the average pairing score against cucumber, pepper, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
