Marinate pork for at least 2 hours or preferably overnight.
Prepare the oven to 375 degrees F. Place pork on the oven rack. Arrange a roasting pan filled with 1/2 cup water. Bake for about 20 minutes and turn to evenly bake the other side for another 20 minutes.
Adjust oven to broil setting. Apply basting sauce and cook for 2 minutes, turning meat once. Cool pork when done then cut into thin portions.
