Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard flour
- Thickens the dressing and adds sharp mustard flavour to the pickle.
- Sugar
- Balances the sharpness of the vinegar and adds sweetness.
- Vinegar
- Acidity that preserves the vegetables and gives the pickle its tang.
- Salad oil
- Adds fat and smoothness to the mustard flour mixture.
The step that matters
Heating the pickle over three mornings. Repeated gentle heating softens the vegetables and helps the flavours blend, while overheating can make the mustard mixture bitter or cause the vegetables to turn mushy.
