Hot Horseradish Sauce
Ingredients
Directions
Mix grated horseradish with brown gravy and let it stand by the fire until just boiling.
Add salt, mustard, and vinegar to the mixture.
For a variation, stew horseradish in vinegar for 10 minutes, drain, and mix with 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 well.
Heat the sauce in a bowl over boiling water until warm.
Serve immediately with meats or store for several days.
