Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Make up the bulk of the sauce and give it its fresh, crisp body.
Onions
Add savoury depth and aroma that rounds out the sharpness of the vinegar.
Red peppers
Add mild sweetness and colour, softening as they cook.
Brown sugar
Adds sweetness that balances the acidity of the vinegar.
Vinegar
Provides the sharp acidity that defines the sauce and helps keep it stable.
Mustard seed
Contributes a pungent, slightly bitter flavour characteristic of mustard.

The step that matters

Drain the chopped cucumbers overnight. Cucumbers are mostly water. Draining them thoroughly removes liquid before cooking, so the sauce stays thick and the vinegar and spices are not diluted into a watery result.

Swap the onion

How well each one fits the dish's main ingredients (cucumber, pepper, sugar, mustard, celery, vinegar):
