Step 1Trim all the fat off the pork and cut the pork into 1-inch-thick slices.
Step 2Combine the ketchup, salt, sugar, garlic, brandy, five-spice powder and honey in a small bowl. Rub this mixture on the pork pieces, covering all sides. Marinate the pork in the refrigerator, covered, for 2 hours or longer.
Step 3Heat the oven to 425 degrees.
Step 4Place the pork on a rack in a roasting pan and cook for 20 minutes. Turn the pork, baste it with the pan juices, and cook for an additional 20 minutes. Reduce the heat to 350 degrees and cook until the pork reaches an internal temperature of 170 degrees, about 20 minutes. Remove from the oven.
Step 5Boil the sauce for a couple of minutes, then brush it over the pork before serving.
