Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the crisp, watery bulk of the salad.
- White onions
- Add sharp flavor and aroma that mellows during the pickling rest.
- Green peppers
- Contribute crunch and a fresh, grassy bite.
- White mustard seed
- Adds a sharp, pungent heat that infuses into the vinegar.
- Black mustard seed
- Adds a stronger, more pungent heat and aroma to the salad.
- Vinegar
- Acidity that preserves the vegetables and gives the salad its tang.
The step that matters
Draining the salted mixture for 24 hours. Salt draws water out of cucumbers and onions through osmosis. Draining removes that liquid so the salad stays crisp rather than diluting the cold vinegar and turning soft.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, pepper, mustard, celery, vinegar):
- Lettucefits better
- Horseradishfits better
- Radishfits better
- Onionthe original
