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

What each ingredient does

Green tomatoes
Provide the bulk of the chowder and soften into the body of the dish as they cook.
Onions
Add savory flavor and body, softening during the salting and boiling.
Vinegar
Adds acidity that sharpens the flavor and helps preserve the mixture.
Sugar
Balances the sharpness of the vinegar and adds sweetness.
Horseradish
Contributes a sharp, pungent heat that gives the chowder its bite.

The step that matters

Salting and draining overnight. Salt draws water out of the tomatoes and onions through osmosis. Discarding that liquid concentrates the flavor and helps the vegetables hold their texture rather than turning watery in the pan.

Swap the tomato
