Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the crisp, bulky body of the pickles that absorbs the dressing.
- Small onions
- Add pungent flavour and firm texture that holds up in the brine.
- Coarse sea salt
- Draws moisture out of the cucumbers and onions so they stay crisp and absorb less liquid.
- Cider vinegar
- Provides the acidity that preserves the pickles and sharpens their flavour.
- Olive oil
- Adds fat and richness that carries the flavour of the mustard and pepper.
- Coleman's mustard
- Contributes sharp pungency and emulsifying help to the oil and vinegar mixture.
The step that matters
Drain the salted vegetables thoroughly in the morning. Salt draws water out of the cucumbers and onions overnight. Any moisture left behind dilutes the vinegar and dressing and softens the vegetables, so draining well keeps them crisp and the pickle well flavoured.
Swap the white pepper
