Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the bulk of the mix and gives the pickle its crisp, firm texture.
- Onions
- Add savory depth and aroma as they soften in the sugar and vinegar brine.
- Green peppers
- Contribute crunch and a fresh, slightly bitter vegetable flavour.
- Red peppers
- Add sweetness and colour, and soften slightly in the brine.
- White sugar
- Sweetens the pickle and balances the sharpness of the vinegar.
- White wine vinegar
- Provides the acidity that preserves the vegetables and gives the pickle its tang.
The step that matters
Heat without boiling. Heating the vinegar and sugar only until the sugar dissolves keeps the vegetables crisp; boiling would soften them further and can drive off aromatic compounds from the mustard and celery seed.
