Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt
- Draws water out of the vegetables overnight, helping them stay crisp and firm.
- White sugar
- Adds sweetness and balances the sharpness of the vinegar.
- White wine vinegar
- Provides acidity that preserves the relish and gives it a tangy flavor.
- White mustard
- Adds pungent flavor and a sharp bite to the relish.
The step that matters
Heat until the sugar melts, but do not boil. Gentle heat dissolves the sugar into the vinegar without overcooking the vegetables. Boiling would soften the cabbage and peppers and can drive off flavor and aroma.
