Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbages
- Form the bulk of the relish and give it a crisp, crunchy texture.
- Peppers
- Add pungent flavour and colour, with finely chopped pieces spreading heat through the jar.
- Mustard seed
- Adds a sharp, pungent bite that mellows as the relish sits in the vinegar.
- Horse-radish
- Contributes a sharp, pungent heat that complements the cabbage and peppers.
- Cold vinegar
- Acts as the preserving liquid, adding acidity that keeps the relish tart and stable.
- Sugar
- Balances the sharpness of the vinegar with a touch of sweetness.
The step that matters
Layering with salt and cold vinegar. Salt draws water out of the cabbage and peppers, and the cold vinegar then covers them so the vegetables stay crisp. Using too little vinegar or leaving pieces exposed can let the relish spoil.
