Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Their crisp, watery flesh becomes the pickle's main texture after salting and soaking.
- Onions
- Add sharpness and body, softening slightly as they sit in the brine and vinegar.
- Olive oil
- Carries the mustard and spices and gives the dressing its richness and body.
- Cider vinegar
- Provides the acidity that preserves the vegetables and gives the pickle its tang.
- Ground mustard
- Adds pungent flavor and helps thicken the oil and vinegar dressing.
The step that matters
Soaking and draining the cucumbers and onions. Brining and repeated draining pull out water so the slices stay crisp rather than soggy. Skipping or shortening these soaks leaves the pickles limp and more diluted in the jar.
Swap the onion
