Why it works: Horseradish and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

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.
