2 T brown sugar
2 T Asian five spice powder
1 t sea salt
1 rack of pork back ribs
1/2 c hoisin sauce
1/2 c peanut sauce
If you are planning to use the broiler to finish the ribs, move one oven rack 5″s from the element and leave one oven rack in the middle of the oven. Preheat the oven to 325 F. Line a baking sheet with 2 layers of aluminum foil, leaving at least 2″ of overhang at each short end. (You will need the extra length to seal up the foil packet.) Make the dry rub by stirring together the sugar, five spice powder and salt, then set aside. Pat the ribs with paper towels if they are very wet, then flip them bone side up. Slip a small knife between the membrane and a bone to loosen the membrane. Peel away the membrane from the underside of the ribs. You may have to loosen it in several places before it comes free. Once the membrane is removed, rub in half of the dry rub mix on the underside of the ribs. Flip the ribs meat side up and place them on the baking sheet, then rub the rest of the dry rub onto the top of the ribs. Place 2 more sheets of foil on top of the ribs, then pinch and roll all 4 edges until the ribs are sealed inside the aluminum foil. Place the baking sheet on the middle rack in the oven and bake for 2 hours. If you are planning to grill the ribs to finish them, prepare your grill as needed to reach medium heat by the time the ribs are done cooking in the oven. If you are planning to use the broiler, you don’t need to do anything else at this time. After 2 hours, take the ribs out of the oven and set aside for a moment. Make the sauce by stirring together the peanut sauce and the hoisin sauce in a bowl. Then, being careful of the steam, slice the top of the packet open and roll the top part of the aluminum foil out of the way.
To Finish on the Grill: Place the ribs on the preheated grill. Baste top of the ribs with the sauce, close the lid and grill for 5 min. Flip the ribs and grill for 5 more min. Ribs are done when the sauce is thickened and fragrant and grill marks begin to appear.
To Finish Under the Broiler: Baste the top of the ribs with the sauce. Place the baking sheet on the oven rack located about 5″ from the element. Broil about 5 min or until the sauce is thick and bubbling all over.
