Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cauliflower
- Provides the firm, crisp bulk of the pickle that holds its texture after brining and boiling.
- Black mustard seed
- Adds a sharp, pungent flavour that develops as the seeds are steeped in vinegar.
- White mustard seed
- Contributes a milder mustard bite alongside the black seed in the pickling liquid.
- Green tomatoes
- Add tartness and body, holding their shape through the brine and boiling.
- Onions
- Contribute sweetness and aroma that mellow during the long vinegar boil.
- Ground mustard
- Thickens and deepens the flavour of the pickling liquid, giving it a sharper mustard character.
The step that matters
Draining after the 24-hour brine. Excess brine left in the vegetables dilutes the vinegar and can make the pickle soft or overly salty, so the mixture should drain well before it is boiled.
