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 and stay crisp or firm after brining and pickling.
- Vinegar
- Provides the acidity that preserves the cucumbers and gives the pickle its sharp flavour.
- Sugar
- Balances the sharpness of the vinegar and rounds out the sweet-sour flavour.
- Horseradish
- Adds a sharp, pungent aroma and heat that mellows during pickling.
The step that matters
Pour the hot vinegar mixture over the cucumbers. The vinegar must be brought to a boil with the sugar so the mixture is hot enough to help seal the jars and keep the cucumbers safe to store. Pouring it cool or lukewarm weakens that protection and can leave the pickles less stable.
Swap the dill
How well each one fits the dish's main ingredients (cucumber, mustard, horseradish, vinegar, sugar):
- Capersfits better
- Tarragonfits about as well
- Dillthe original
- Allspicefits less well
Fit is the average pairing score against cucumber, mustard, horseradish, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
