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 pickle once salted and dressed.
- Onions
- Add sharpness and savory sweetness that mellows during the soak.
- Coarse sea salt
- Draws water out of the sliced vegetables, firming them and removing excess brine.
- Vinegar
- Provides the acidity that preserves and sharpens the pickle.
- White mustard seed
- Adds a mild, pungent bite and texture to the dressing.
- Black mustard seed
- Contributes a sharper, more intense mustard heat to the dressing.
The step that matters
Pour off the brine. Salt draws water out of the cucumbers and onions; if the liquid is not fully poured off, the pickle stays watery and dilutes the vinegar dressing, reducing crispness and keeping flavour weak.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, vinegar, olive, mustard, celery):
- Lettucefits better
