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

What each ingredient does

Cucumbers
Provide the bulk of the catsup and release moisture when salted, giving a crisp, fresh texture.
Onions
Add sharp, savory flavour and aromatic body to the mixture.
White mustard seed
Contributes pungent, sharp flavour that develops as the seeds soften in the vinegar.
Celery seed
Adds a warm, earthy aroma that complements the cucumber and onion.
Cold vinegar
Provides acidity that preserves the mixture and sharpens its flavour.

The step that matters

Draining the salted cucumbers overnight. Salt draws water out of cucumber by osmosis. Draining well removes that liquid, so the catsup stays thick and crisp rather than watery once it is covered with vinegar.

Swap the onion
