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 body and tart flavor of the sauce.
Coarse sea salt
Draws water out of the vegetables overnight, concentrating their flavor and firming the texture.
Sugar
Adds sweetness that balances the sharpness of the vinegar and green tomatoes.
Vinegar
Adds acidity that gives the sauce its tang and helps preserve it.
Horseradish
Contributes a sharp, pungent heat that mellows during slow stewing.

The step that matters

Drain off the water after salting. Salt draws liquid out of the vegetables overnight. Pouring off that liquid removes excess water and salt, so the sauce thickens properly and does not turn overly salty or thin during the long stew.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper, sugar, horseradish, clove, cinnamon, vinegar):

  1. Mustardfits better
  2. Capsicumfits better
  3. Cucumberfits better
  4. Onionthe original
