Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Adds sharp, pungent flavor that cuts through the richness of the fat.
- Horseradish
- Contributes a sharp, pungent heat that gives the sauce its character.
- Vinegar
- Adds acidity that brightens the sauce and balances the fat.
- Oil or butter
- Provides fat that gives the sauce a smooth, rounded body and mouthfeel.
- Thickening material
- Thickens the liquid so the sauce clings to food.
The step that matters
Stew the mixture together well. Gentle, thorough simmering blends the mustard, horseradish, vinegar and fat into one emulsified sauce. Stewing too hard or too briefly can leave it separated or harsh-tasting.
