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 gives the pickle its tang and helps preserve it.
Sugar
Adds sweetness that balances the sharpness of the vinegar.
Flour
Thickens the mustard dressing so it coats the vegetables.
Mustard
Supplies the pungent, sharp flavour characteristic of chow chow.
Turmeric
Gives the pickle its bright yellow colour and a mild earthy aroma.

The step that matters

Cooking the vegetables until tender. Vegetables cooked past tender turn soft and mushy, while under-cooked pieces stay raw and crunchy. Stopping at tender keeps each vegetable's texture firm enough to hold up in the vinegar dressing.

Swap the onion
