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

What each ingredient does

Cabbage
Forms the bulk of the relish and provides a crisp, fresh texture.
Peppers
Provide the main body and pungent flavor of the sauce.
Cider vinegar
Adds acidity that sharpens flavor and helps preserve the sauce.
Horseradish
Contributes a sharp, pungent heat that mellows as the sauce stands.
Sugar
Balances the sharpness of the vinegar with sweetness.

The step that matters

Pour the boiling mixture over the vegetables. The mixture must be fully boiling when poured so the hot vinegar softens the cabbage and peppers and begins to sterilize and preserve the sauce.
