Fine Horseradish Sauce
Ingredients
Directions
Prepare the horseradish
Wash, wipe, and scrape the horseradish root to remove the outer skin.
Grate the horseradish on a very fine grater until it becomes a pulp.
Make the sauce
In a bowl, combine the grated horseradish, salt, sugar, and vinegar.
Stir the vinegar in gradually while mixing the other ingredients until smooth.
Add garlic or shallot vinegar if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Horseradish
- Supplies the sharp, pungent heat that defines the sauce.
- Vinegar
- Adds acidity that sharpens flavour and balances the sugar.
- Sugar
- Softens the sharpness of the horseradish and vinegar with sweetness.
The step that matters
Grating the horseradish. Fine grating breaks the root's cells and releases the volatile compounds that give pungency. Heat builds as the pulp sits and the compounds form, so the sauce can change strength over time. Adding vinegar soon after grating helps stop that reaction and fix the heat level.
Swap the garlic
The recipe marks garlic as optional. How well each one fits the dish's main ingredients (horseradish, sugar, vinegar):
- Cinnamonfits better
- Capersfits better
- Tarragonfits better
- Garlicthe original
Fit is the average pairing score against horseradish, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
