Why it works: Horseradish and mustard 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 ↓
Hot Horseradish Sauce
Ingredients
Directions
Make the sauce
Mix grated horseradish with brown gravy and let it stand by the fire until nearly boiling.
Add salt, made mustard, and garlic or eschalot vinegar (or substitute with common vinegar).
In a small basin, combine cayenne pepper, salt, and sugar.
Pour in lemon juice, Harvey's sauce, mushroom catsup, and port wine; mix thoroughly.
Heat the sauce by placing the basin in a saucepan of boiling water.
Serve
Serve immediately with meats like geese, ducks, roast pork, or venison.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated horseradish
- Provides the sharp, pungent heat that defines the sauce.
- Brown gravy
- Forms the liquid base that carries the other flavours.
- Made mustard
- Adds sharpness and pungency that complements the horseradish.
- Port wine
- Adds sweetness and depth of flavour to the sauce.
- Lemon juice
- Adds acidity that brightens the sauce and balances richness.
The step that matters
Heat the sauce in a water bath. Horseradish loses its pungency when overheated or boiled for long, so gentle heating over boiling water keeps the sauce warm while preserving its sharp flavour.
Swap the lemon
How well each one fits the dish's main ingredients (horseradish, mustard, garlic, pepper, sugar, sauce, mushroom):
