Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Adds fat that gives the sauce a smooth, rich body.
- Butter or cream
- Adds fat and creaminess, softening the sharp horseradish heat.
- Mustard
- Adds sharp flavour and helps emulsify the fat with the liquids.
- Grated horseradish
- Provides the pungent, sharp heat that defines the sauce.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness.
The step that matters
Stir and beat until thoroughly mixed. Vigorous mixing helps the fat and the acidic, watery ingredients combine into a smooth, evenly seasoned sauce. Incomplete mixing leaves pockets of intense horseradish heat and an uneven, separated texture.
