Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Vinegar
Provides the sharp acidity that preserves the vegetables and balances the sweetness.
English mustard
Adds pungent heat and sharp flavour to the dressing.
Turmeric
Gives the pickle its yellow colour and an earthy aroma.
Sugar
Softens the sharpness of the vinegar and adds sweetness.
Olive oil
Carries the spices into the paste and adds richness to the dressing.
Cauliflower
Forms the firm, crunchy bulk of the pickle that holds its texture in the brine.

The step that matters

Stir the paste into the boiling vinegar constantly until it thickens. Mustard and flour-free spice pastes can scorch or separate if left unstirred, and the mixture only thickens evenly when it is kept moving over the heat. Constant stirring keeps the paste dispersed so the dressing stays smooth and coats the vegetables.

Swap the onion
