Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the acidity that preserves the relish and gives it its sharp, tangy flavour.
- Brown sugar
- Adds sweetness and balances the sharpness of the vinegar.
- Flour
- Thickens the hot vinegar mixture so it clings to the vegetables.
- Ground mustard
- Adds sharp, pungent flavour to the sauce.
- Cauliflower
- Forms the firm, crisp bulk of the relish that holds its texture after pickling.
The step that matters
Scald the vinegar mixture while stirring constantly. Flour settles and clumps quickly when heated without constant stirring, leaving lumps and an uneven, pasty sauce instead of a smooth, thickened one.
Swap the onion
