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.
Swap the mace
