1. Wash pork roast and pat dry. Add salt and pepper to taste. Wrap pork roast in uncooked bacon slices, securing underneath the roast. Cook in crockpot on low heat for about 5 to 6 hours or until bacon is cooked and roast is tender. Transfer to serving platter. 2. Pour broth into a sauce pan and bring to a boil. Thicken using about 2 teaspoons of cornstarch mixed with enough milk to make a pourable paste. Add cornstarch mixture to broth a little at a time, whisking constantly. If mixture seems too thin, you may add a little more cornstarch. If too thick, pour in a little milk or water. Continue cooking and whisking until consistency is correct. You may also add salt and pepper to taste. 3. Slice roast and serve with gravy.
