Preheat your oven to 300 degrees
Rinse the ribs and pat them dry. Remove the membranes from the back of the ribs. Place the ribs on a baking sheet and brush the ribs generously with the mustard. Combine the sugar, paprika, chili powder, cayenne, and salt in a small bowl. Sprinkle this mixture over both sides of the ribs. Grind fresh pepper over the ribs. Place the ribs in an aluminum roasting bag and add the water. Seal the bag tightly, place on a baking sheet, and put in the oven. Slowly cook the ribs for 45 minutes to 1 hour. Remove the bag from the oven and let the ribs cool in the roasting bag for 30 minutes. Open the bag away from you in case there is residual steam. The ribs are ready for the next step when you can grab them with a pair of tongs, lift them up, and they bend easily. Then oil the grill racks. Prepare your grill, closed lid for 10 to 12 minutes. When the grill is hot, place the ribs, meaty side down, on the grill. Close the lid and cook for about 15 minutes, then turn. Brush the seared side with the barbecue sauce, cover again, and cook for another 10 to 15 minutes. Turn, brush with sauce, cover, and let them enjoy the heat for another 10 minutes. Brush the same side with sauce again, cover, and cook for no more than 5 minutes. Uncover, drizzle the ribs with the honey, and let them stay on the heat a couple of minutes more to allow the honey to glaze. Remove and serve to hoots and hollers.
