Mix one third cup of nonfat sour cream with 1 teaspoon of prepared white horseradish. Add salt and pepper, mixed in one-half tablespoon of minced shallots. Stir well and store in air tight container for 30 minutes before using to allow the flavors to mix. Serve as a dipping sauce for steak or spread on a bun for a tangy hamburger you will not forget. Enjoy!
