Directions
Prepare the vegetables

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 relish, giving crunch that holds up through the long pickling.
- White onions
- Add sharpness and aroma that mellow during the salt and vinegar rest.
- Coarse sea salt
- Draws water out of the cabbage and onions, firming them and concentrating flavour.
- Brown sugar
- Adds sweetness and depth that balances the vinegar's acidity.
- White mustard seed
- Provides the pungent mustard bite and texture of the pickle.
- Cider vinegar
- Supplies the acidity that preserves the pickle and gives it tang.
The step that matters
Squeezing out excess liquid. Removing water after the salt and vinegar rest keeps the chow-chow crisp and stops it from thinning or spoiling in the jar.
