Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the acidity that preserves the vegetables and gives the pickle its sharp taste.
- Black mustard seed
- Adds pungent, sharp flavour to the pickling liquid as it steeps in the hot vinegar.
- White mustard seed
- Adds milder pungent flavour and a slight bite to the pickling liquid.
- Cucumbers
- Firm vegetables that soften slightly in the hot brine while keeping some crunch.
- Cauliflower
- Firm florets that soften in the hot brine while holding their shape and absorbing flavour.
- Mustard
- Adds sharp flavour and body to the vinegar mixture that coats the pickles.
The step that matters
Adding the mustard after cooling. Mustard's sharp flavour is volatile and dulls with prolonged heat, so mixing it in once the liquid has cooled keeps the pickle bright and pungent.
