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

What each ingredient does

Green peppers
Provide the bulk of the sauce and its fresh, vegetal flavor.
Cabbage
Adds crunch and body that holds up to the hot vinegar.
Vinegar
Provides the sharp acidity that gives the sauce its tang and preserves it.
Horseradish
Contributes pungent heat that mellows as the sauce stands.
Sugar
Balances the vinegar's sharpness with a touch of sweetness.

The step that matters

Pour the hot vinegar mixture over the vegetables while it is still hot. Hot vinegar softens the cabbage and peppers and draws flavor from the spices into them, so pouring it while hot helps the sauce soak through evenly. Letting it cool first would leave the vegetables firmer and less infused.

Swap the mace

How well each one fits the dish's main ingredients (pepper, cabbage, horseradish, mustard, allspice, clove, sugar):

  1. Cinnamonfits better
  2. Turmericfits better
