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 vinegar of choice.
For a variation, stew horseradish in vinegar for 10 minutes, drain, and mix with nearly ½ pint of thick melted butter.
In a small bowl, combine cayenne pepper, salt, and sugar.
Pour in lemon juice, Harvey's sauce, mushroom catsup, and port wine; mix thoroughly.
Heat and serve
Heat the sauce by placing the bowl in a saucepan of boiling water.
Serve immediately with meats or fish, or let it sit for a few hours for better flavor.

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
- Supplies the liquid base and savory body of the sauce.
- Made mustard
- Adds sharpness and a mild pungency that balances the richness.
- Vinegar
- Adds acidity that brightens the flavor and sharpens the heat.
- Port wine
- Adds sweetness and depth of flavor.
- Lemon juice
- Adds fresh acidity that lifts the other flavors.
The step that matters
Heat the sauce by placing the bowl in a saucepan of boiling water.. Gentle indirect heat warms the sauce evenly without curdling or scorching it. Pouring it over direct high heat can make it separate or turn bitter, and horseradish loses its pungency when overheated.
Swap the lemon
