Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Green tomatoes
Bulk vegetable; brining draws out water so the pieces stay firmer.
Cabbage
Adds bulk and body to the chopped mixture.
String beans
Adds bulk and a firm, tender texture.
Brown sugar
Adds sweetness that balances the sharpness of the vinegar.
White mustard seed
Adds a sharp, pungent spice note to the mixture.
Vinegar
Adds acidity that helps preserve the mixture and sharpens its flavour.

The step that matters

Brining the sliced tomatoes. Soaking the sliced tomatoes in a brine strong enough to float an egg matters because salt draws water out of the vegetables, firming them and reducing spoilage. Squeezing out the brine afterward removes excess salt and liquid.
