Ingredients
Directions
Prepare the cucumbers
Freshen cucumbers in cold water for 3-4 hours and remove them.
Place them in a stone jar and sprinkle liberally with coarse sea salt.
Let stand for 24 hours, then pour off the brine.
Pickle and pack
Add onions, green peppers, white pepper, and sugar.
Cover with vinegar and let stand for 8 days.
Pour off the vinegar and boil it for 10 minutes.
Place pickles in glass jars and pour the hot vinegar over them.
Seal the jars and keep in a dark place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the pickle, becoming crisp-firm after salting and curing.
- Coarse sea salt
- Draws water out of the cucumbers, firming them and preparing them to take up brine flavour.
- White sugar
- Adds sweetness that balances the sharp vinegar and helps define the pickle's sweet-sour character.
- Vinegar
- Provides the acidity that preserves the pickles and gives them their sour bite.
- Small onions
- Contribute aromatic sharpness and sweetness that mellow during the long soak.
The step that matters
Pouring off the brine after salting. Salt draws water out of the cucumbers. Rinsing or skipping the pour-off leaves them overly salty, while leaving them too long can soften the texture.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, onion, pepper, sugar, vinegar):
- Garlicfits better
- Tarragonfits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against cucumber, onion, pepper, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
