Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the main bulk and tart body of the pickle, softened by salting and cooking.
- Cabbage
- Adds bulk and a crisp-tender texture that holds up during long cooking.
- Vinegar
- Supplies the acidity that preserves the pickle and gives it its sharp flavor.
- Sugar
- Balances the sharpness of the vinegar and tomatoes with sweetness.
- Onions
- Add savory depth and aromatic flavor as they soften during cooking.
The step that matters
Salting the green tomatoes overnight. Salt draws water out of the tomatoes through osmosis, firming their texture and reducing excess liquid. Skipping or shortening this step leaves the pickle watery and soft.
Swap the onion
