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 and aroma that define the sauce.
- Brown gravy
- Provides the liquid base and savoury depth for the sauce.
- Made mustard
- Adds sharpness and helps the sauce taste rounded.
- Vinegar
- Adds acidity that brightens the sauce and sharpens the horseradish.
- Butter (in the method)
- Adds richness and a thicker, smoother body to the sauce.
The step that matters
Stew the horseradish in vinegar for 10 minutes. Horseradish's pungent compounds are volatile and fade with prolonged heat. Stewing for the stated time softens the raw bite while the vinegar's acidity helps keep the flavour sharp, so overcooking can leave the sauce dull.
