Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the crisp, bulk body of the salad.
- Onions
- Add sharpness and savour that mellows during the salted rest.
- Coarse sea salt
- Draws water out of the cucumbers and onions, firming their texture.
- Cider vinegar
- Adds acidity that preserves the salad and sharpens its flavour.
- Mustard seed
- Contributes a pungent, slightly bitter bite when mixed with the spices.
The step that matters
Drain the cucumbers as dry as possible. Salting pulls water out of the vegetables, but any water left behind dilutes the vinegar and makes the salad soggy and less crisp. Thorough draining keeps the texture firm and the dressing concentrated.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, mustard, celery, pepper, cider, vinegar):
