Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White spine cucumbers
- Provide the main crisp, watery vegetable base of the relish.
- White onions
- Add sharp, pungent flavor that mellows during long pickling.
- Green peppers
- Add fresh, grassy crunch and bulk to the mixture.
- Black mustard seed
- Contributes sharp, pungent heat that infuses into the vinegar over time.
- White mustard seed
- Adds milder pungency and a familiar mustardy bite.
- Coarse sea salt
- Draws moisture out of the vegetables, firming their texture during draining.
The step that matters
Draining the mixture for 24 hours. Salt draws water out of the cucumbers, onions and peppers. Draining removes that liquid so the vegetables stay crisp and the vinegar is not diluted in the jar.
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
