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

What each ingredient does

Vinegar: Provides acidity that sharpens flavour and helps preserve the pickling liquid.
White mustard seed: Adds sharp, pungent flavour as its compounds release into the liquid.
Black mustard seed: Adds a sharper, more pungent bite than the white seed.
Horseradish: Contributes pungent heat that infuses into the vinegar.
Brown sugar: Adds sweetness that balances the sharpness of the vinegar.
Turmeric: Gives the liquid its yellow colour and a earthy aroma.

The step that matters

Letting the mixture sit. Spices need time in the vinegar to release their oils and flavour into the liquid. Stirring frequently spreads them evenly, and keeping the jar covered limits evaporation and contamination.
