Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the bulk of the pickle and keeps a firm, crisp bite after cooking.
- Green tomatoes
- Add tartness and body, helping the relish hold together as it cooks.
- Onions
- Add savory depth and sweetness that mellows during slow cooking.
- Vinegar
- Provides acidity that preserves the pickle and sharpens its flavor.
- Brown sugar
- Balances the vinegar's sharpness and adds caramel notes as it cooks.
The step that matters
Cook all together slowly for 4 hours. Long, gentle cooking lets the vinegar and sugar penetrate the vegetables and blend the spices. Cooking too hot or too briefly can leave the vegetables harsh or the flavors separate, and the sugar can scorch on the bottom of the pan if not stirred.
