Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, firm body that the pickle is built around.
- White onions
- Add sharp, savoury flavour that mellows as the pickle sits.
- Olive oil
- Carries the spices and adds richness and a smooth mouthfeel.
- White mustard seed
- Contributes pungent, sharp flavour to the pickling mixture.
- Cold vinegar
- Provides the acidity that gives the pickle its tang and preserves it.
The step that matters
Rinse the cucumbers after salting. Salt draws water out of cucumbers and makes them firm, but leftover salt will make the finished pickle too salty. Rinsing and tasting lets you control the final seasoning.
Swap the nutmeg
How well each one fits the dish's main ingredients (cucumber, onion, mustard, pepper, celery, olive, vinegar):
- Tarragonfits better
- Garlicfits better
