Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the main body of flavour and bulk for the pickled liquid.
- Vinegar
- Acidity that preserves the mixture and gives it its sharp, tangy character.
- Onions
- Add sweetness and aroma that mellow as the mixture stands.
- Salt
- Draws moisture out of the cucumbers and seasons the liquid.
The step that matters
Boil the mixture, then let it cool. Boiling heats the vinegar mixture enough to help stabilise it for storage, and cooling before straining keeps the liquid clear and safe to handle. Skipping the cooling or rushing the boil can leave the flavour harsh or the keeping quality poor.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, vinegar, shallot, garlic, pepper):
