Why it works: Mustard and horseradish 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 ↓
Horseradish Sauce
Ingredients
Directions
In a bowl, combine mustard and salt.
Work in cream until smooth.
Add vinegar and grated horseradish, mixing well.
If the sauce is too thick or hot, add more cream to adjust consistency.
Omit mustard if a milder flavor is preferred.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Adds moisture and softens the sharp heat, giving the sauce a smooth, spoonable texture.
- Grated horseradish
- Provides the sharp, pungent heat that defines the sauce.
- Vinegar
- Adds acidity that brightens the flavor and sharpens the horseradish aroma.
- Mustard
- Contributes sharpness and helps emulsify the cream into a smooth sauce.
The step that matters
Work in cream until smooth. Cream must be incorporated gradually so the mixture stays smooth rather than lumpy or separated. Adding it slowly lets the fat and liquid combine evenly with the mustard, and extra cream can be added afterward to correct thickness or heat.
