Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cauliflowers
- Form the bulk of the pickle and absorb the tangy liquid, becoming tender and crisp-firm.
- Vinegar
- Provides the acidity that preserves and sharpens the pickle.
- Mustard
- Adds pungent flavour and body to the pickling liquid.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Red peppers
- Add sweetness, colour and a mild aroma to the jar.
The step that matters
Pouring the hot mixture over the cauliflowers. The liquid must be fully boiling when poured so it penetrates the vegetables evenly and sits at a temperature that helps the jar seal safely. Pouring cooled or lukewarm liquid leaves the pickle under-penetrated and less stable.
