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.
