  1. Preheat the oven to 225 degrees F.
  2. In a roasting pan with a cover, place the meat. Cover and bake in the preheated oven for 3-1/2 hours or until tender.
  3. Remove from the oven. Increase the oven temperature to 350 degrees F.
  4. In a small bowl, mix the brown sugar and mustard. Spread the mixture over the meat. Bake uncovered for 15 minutes.
  5. In a large saucepan, boil the potatoes in enough water to cover for 8 to 10 minutes or until tender. Drain.
  6. In a bowl, whisk together the sour cream, butter/margarine, horseradish, salt, and white pepper.
  7. Pour the mixture over the potatoes. Using a rubber scraper, mix gently to coat evenly. Serve with the meat.
