3. Pour 1/4 cup of water into the bottom of the pan and cover the pan tightly with aluminum foil
4. Cook pork for 20 minutes, remove foil and continue to cook the pork until the edges begin to brown, about 35-45 minutes depending on how thick your slices are
5. Turn on broiler and broil until pork begins to caramelize (about 7-9 minutes)
6. Remove the pan from oven and brush with glaze and place it back under the broiler for 3-5 minutes. 
7. Remove the pork from the oven, flip the pork over,  and broil the other side for 7-9 minutes 
8. Add the glaze to that side of the pork and broil again for 3-5 minutes.
