Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Main vegetable; salting draws out water so the pickles stay crisp.
- Coarse sea salt
- Draws water out of the cucumbers and onions, firming their texture and seasoning them.
- Small onions
- Adds sharp, savory flavor and bulk to the pickle mixture.
- Olive oil
- Adds fat and richness, coating the vegetables and carrying spice flavor.
- Cold vinegar
- Adds acidity that preserves the pickles and gives them their tang.
- White mustard seed
- Contributes pungent, sharp flavor that deepens as the pickles sit.
The step that matters
Drain and dry the cucumbers. Salt draws water out of the cucumbers, but any moisture left on them dilutes the oil and vinegar and weakens the brine. Thorough drying helps the pickles stay crisp and well flavored.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, onion, mustard, celery, olive, vinegar):
- Capersfits better
- Tarragonfits better
- Garlicfits better
- White pepperthe original
