This sauce is traditionally served in England with roast beef.
- Mix grated horseradish, vinegar, salt and sugar in a bowl.
- Stir in the half whipped cream.
- Serve immediately, or chill until ready to serve.
The fresher the horseradish, the stronger the flavor.
For a German style horseradish sauce, with a sharper taste, substitute vinegar with the same amount of lemon juice, and whipping cream with sour cream, or omit altogether.
A warm horseradish sauce can be prepared by adding 2-3 tablespoons grated horseradish, 1/2 teaspoon sugar, and 1-2 tablespoons vinegar to 2 cups of bechamel or white sauce. Heat the sauce gently before serving. Do not allow to boil.
To get a smooth texture, process the sauce, lightly, in the blender.
