Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the sauce and break down into a soft, thick texture when cooked.
- Brown sugar
- Adds sweetness and helps balance the sharp acidity of the vinegar.
- Vinegar
- Adds acidity that sharpens flavor and helps preserve the sauce.
- Cabbage
- Adds bulk and body, softening as it cooks into the sauce.
- Coarse sea salt
- Draws juice out of the chopped vegetables, reducing their water before cooking.
The step that matters
Pressing out the juice. Salting draws water from the chopped vegetables, and leaving that liquid in would thin the sauce and dilute its flavor. Pressing it all out before cooking keeps the final texture thick.
