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

What each ingredient does

Green tomatoes
Provide the bulk of the pickle and release moisture that mingles with the vinegar.
Cabbage
Adds crisp texture and body that holds up during long simmering.
Onions
Contribute savory depth and aroma as they soften during cooking.
Brown sugar
Adds sweetness that balances the sharpness of the vinegar.
Vinegar
Acts as the preserving liquid and supplies the tangy acidity.
Mustard seed
Adds pungent, nutty flavour when cooked in the vinegar.

The step that matters

Boiling the mixture slowly for 2 hours. Long, gentle simmering softens the chopped vegetables and lets the vinegar and sugar penetrate them. A hard, fast boil can scorch the sugar on the bottom of the pot and make the pickle uneven.
