Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gherkins
- Form the main body of the pickle and absorb the vinegar and spiced brine flavour.
- Best vinegar
- Provides the acidity that preserves the gherkins and gives the pickle its sharp tang.
- Brown sugar
- Balances the sharpness of the vinegar with sweetness and adds depth of flavour.
- Coarse sea salt
- Draws water out of the gherkins and helps firm their texture during brining.
The step that matters
Slowly bring the gherkins and vinegar to a scald. Heating gently lets the vinegar penetrate the gherkins and keeps them firm. Boiling hard too fast can soften the cucumbers and make the pickle mushy.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, sugar, pepper):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Onionthe original
Fit is the average pairing score against vinegar, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
