Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, sliced body of the pickle that the brine penetrates.
- Coarse sea salt
- Draws water out of the cucumbers and onions, firming them and concentrating flavor.
- White wine vinegar
- Provides the acidity that preserves and sharpens the pickle.
- Olive oil
- Adds fat and a rounded mouthfeel to the brine.
- Alum
- Helps the cucumber slices stay firm and crisp during pickling.
The step that matters
Draining thoroughly after salting. Salt draws water out of the cucumbers and onions. If excess liquid remains, it dilutes the vinegar brine and leaves the pickles soft and watery rather than crisp.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, onion, mustard, celery, white wine, vinegar, olive):
- Tarragonfits better
- Garlicfits better
- Capersfits better
- White pepperthe original
