Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Form the crisp-tender body of the pickle, becoming tender when boiled but not falling apart.
- Vinegar
- Acidifies the brine, preserving the beans and giving the pickle its sharp flavour.
- Sugar
- Balances the sharpness of the vinegar, adding sweetness to the brine.
- Whole white mustard
- Adds a sharp, pungent aroma and flavour to the pickling liquid.
- Grated horse-radish
- Contributes pungent heat that mellows as the beans sit in the brine.
The step that matters
Pour the hot vinegar over the beans in the jars. The vinegar must be hot and cover the beans fully. Hot brine helps the jars seal and keeps the beans submerged, which limits spoilage by exposing them to air.
Swap the beans
How well each one fits the dish's main ingredients (mustard, horse, radish, vinegar, sugar):
- Beansthe original
- Sesamefits about as well
- Chestnutfits less well
- Lentilsfits less well
Fit is the average pairing score against mustard, horse, radish, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
