I am a little behind now. I have been down with a very bad cold. This sauce will take no cooking, but goes very well with the brisket. I will get some sides done in a few days. Sorry.
2 teaspoons prepared horseradish
½ teaspoon fresh dill-weed, minced
¼ teaspoon garlic salt
3/4 cup heavy cream, whipped
Sprig of fresh dill for garnish
