Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Their watery flesh firms and turns crisp when brined, giving the pickle its crunch.
- Ground mustard
- Supplies the sharp, pungent flavor that defines a mustard pickle.
- Vinegar
- Adds acidity that sharpens the flavor and helps preserve the vegetables.
- Sweet oil
- Adds fat that carries flavor and gives the pickle a smoother mouthfeel.
The step that matters
Soaking the cucumbers and beans in strong brine for 24 hours. Salt draws water out of the vegetables through osmosis, which firms their texture. Too weak or too short a soak leaves them soft, and the brine also seasons them through, so the strength and timing matter.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, beans, pepper, mustard, vinegar):
- Lettucefits better
- Horseradishfits better
- Radishfits better
- Onionthe original
Fit is the average pairing score against cucumber, beans, pepper, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
