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):
