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

What each ingredient does

Beets
Provide the bulk and the deep color and earthy sweetness of the relish.
Cabbage
Adds crunch and body that holds up through the vinegar.
Horseradish
Supplies the sharp, pungent heat that defines the relish.
Sugar
Balances the sharpness of the vinegar and horseradish with sweetness.
Boiling vinegar
Acidifies the relish, adding tang and helping preserve it.

The step that matters

Filling the jars with boiling vinegar. Jars must be completely filled with boiling vinegar so no air pockets remain. Trapped air can allow spoilage and loss of quality, and sealing hot helps create a vacuum that keeps the relish stable.

Swap the cabbage
