Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Grate the horseradish root finely.
In a bowl, mix the grated horseradish with mustard powder.
Mix and rest
Add vinegar, salt, and sugar to the mixture.
Stir until well combined and let it sit for 30 minutes before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Horseradish
- Provides the sharp, pungent heat that defines the condiment.
- Mustard powder
- Adds sharp, pungent flavor and body to the mixture.
- Vinegar
- Adds acidity that sharpens the flavor and balances the heat.
- Sugar
- Softens the sharpness by adding a touch of sweetness.
The step that matters
Letting it sit for 30 minutes. The pungent heat from mustard and horseradish develops once they are mixed with liquid and then mellows as the mixture rests. Tasting too early can make the heat seem harsher or flatter than it will be, so the resting time lets the flavor settle and blend.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
