1. Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius).
2. Place meat in heavy-bottomed baking dish. Season with spices.
3. In a small bowl, mix ingredients for the sauce. Pour over meat. Cover baking dish tightly.
4. Bake for about three to three and a half hours, depending on the size of the roast. Check for doneness with a fork — it should slide in and out very easily, and the meat should be tender to the touch.
