Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk and acidity that give the pickle its body and tang.
- String beans
- Add crisp-tender texture and bulk to the pickle.
- White onions
- Add savory depth and aroma as they soften during the long boil.
- Cabbage
- Adds bulk and a firm, crunchy texture that holds up through cooking.
- Brown sugar
- Adds sweetness that balances the vinegar's sharpness.
- White mustard seed
- Contributes sharp, pungent flavour that mellows during long cooking.
The step that matters
Boil for three hours under vinegar. Long simmering in vinegar softens the vegetables and blends the spices, but too little time leaves them raw and sharp, while the vinegar must fully cover the mixture so it cooks evenly and preserves well.
