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 pickles, giving the crunchy bite they are known for.
- Alum
- Helps the cucumbers stay firm and crisp during pickling.
- Mustard
- Adds sharp, pungent flavor that balances the vinegar.
- Oil
- Adds richness and carries the flavors of the spices through the pickles.
- Cold vinegar
- Provides acidity that preserves and sharpens the pickles.
The step that matters
Dissolve the alum fully in hot water. Alum firms the cucumber texture, but undissolved lumps can sit unevenly on the pickles and make some pieces hard or gritty. Fully dissolving it lets it spread evenly through the mixture.
Swap the nutmeg
How well each one fits the dish's main ingredients (cucumber, onion, pepper, celery, mustard, vinegar):
- Tarragonfits better
- Dillfits better
- Capersfits better
- Nutmegthe original
Fit is the average pairing score against cucumber, onion, pepper, celery, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
