Why it works: Horseradish and vinegar are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,609 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Excellent Horseradish Sauce
Ingredients
Directions
Prepare
Wash and wipe the horseradish, then scrape off the outer skin.
Grate the horseradish as finely as possible.
Make the sauce
In a bowl, mix the grated horseradish with salt and heavy cream.
Stir in the vinegar, using chili vinegar if the horseradish is mild.
Heat the sauce
To heat the sauce, place it in a clean saucepan over low heat, stirring continuously until just before simmering. Do not let it boil.

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 sauce.
- Heavy cream
- Adds fat and body, softening the sharpness of the horseradish.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the sauce.
The step that matters
Heating the sauce without boiling. Boiling cream can cause it to separate and become grainy, and high heat drives off the volatile compounds that give horseradish its pungency. Heating gently over low heat keeps the sauce smooth and sharp.
