Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White wine vinegar
- Provides the sharp acidity that preserves the pickles and gives them their tang.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Black mustard seed
- Adds pungent, earthy flavor to the vinegar mixture.
- Dry salt
- Draws water out of the cucumbers and seasons them, helping them stay firm.
The step that matters
Keep the pickles hot without boiling. Holding them just below a boil lets the salty, vinegary brine penetrate gradually. A full boil would soften the cucumbers and leave them limp and mushy.
Swap the mace
How well each one fits the dish's main ingredients (white wine, vinegar, sugar, mustard, allspice, celery, horseradish):
- Tarragonfits better
- Cinnamonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against white wine, vinegar, sugar, mustard, allspice, celery, horseradish. Candidates are from the same food group and used in at least 100 recipes.
