Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the vinegar sauce so it coats the vegetables.
- Dry mustard
- Adds sharp, pungent flavour to the sauce.
- French mustard
- Adds mustard flavour and body to the sauce.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Vinegar
- Provides acidity that preserves the pickles and sharpens the flavour.
The step that matters
Stirring while the mixture cooks. The thickened mustard sauce contains flour and sugar, which can scorch on the bottom of the pan during the 30-minute simmer. Constant stirring prevents burning and keeps the sauce smooth.
