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.
- Brown gravy
- Supplies the savoury liquid base and body of the sauce.
- Made mustard
- Adds sharpness and depth of flavour that complements the horseradish.
- Vinegar
- Adds acidity that brightens the sauce and balances its richness.
The step that matters
Stew the horseradish in vinegar for 10 minutes. Heat drives off the volatile compounds that give horseradish its pungency, so over-stewing leaves the sauce mild and flat. Keep the time to the recipe's 10 minutes and watch the heat.
