Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, firm body of the pickles; salting draws out water first.
- Onions
- Add savory sweetness and bulk that softens slightly as they stand in the brine.
- Cider vinegar
- Supplies the acidity that preserves the vegetables and gives the pickle its sharp flavour.
- Olive oil
- Adds fat and a mellow, rounded richness to the pickling liquid.
- Mustard seed
- Contributes a pungent, toasty bite that flavours the pickling mixture.
The step that matters
Draining the salted cucumbers. Salt pulls water out of the cucumbers, and if they are not drained well the excess liquid dilutes the vinegar and makes the pickles soft and watery.
Swap the white pepper
