Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the bulk of the pickle, staying crisp when salted and kept cool.
- Black mustard seed
- Adds sharp, pungent flavor that mellows during the pickling period.
- White mustard seed
- Contributes a milder, sharper bite alongside the black mustard seed.
- Olive oil
- Carries the mustard seed flavor and adds richness to the brine.
- Vinegar
- Provides the acidity that preserves the vegetables and gives them tang.
- Onions
- Add sharpness and aroma that mellow as the pickle matures.
The step that matters
Salting the cucumbers and onions overnight. Salt draws water out of the vegetables through osmosis. Draining and washing afterward removes excess salt, and skipping this step leaves the pickles soft and overly salty.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, mustard, celery, olive, vinegar):
- Lettucefits better
