Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provides the bulk and firm texture of the pickle.
- Onions
- Adds savoury flavour that mellows during long cooking.
- Cauliflowers
- Adds bulk and a tender texture after boiling.
- Mustard
- Provides the sharp, pungent flavour that defines the pickle.
- Red peppers
- Adds mild sweetness and colour.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the pickle.
The step that matters
Salting and draining overnight. Coarse salt draws water out of the sliced vegetables through osmosis. Removing this water keeps the vegetables firmer and stops them diluting the vinegar, so the finished pickle stays crisp rather than soggy.
