Preheat the oven to 200F.

Mix together the salt, pepper and sugar. Rub all over the pork.

Cover an oven tray with a large piece of foil. Place the pork on the foil. Take another large piece of foil. Cover the pork loosely and crimp the sides.

Roast in a 200F oven for two to three hours. For best results, check the meat after two hours, slice off a small piece and try the meat. If you’re happy with the tenderness, remove from the oven.

While the pork roasts, mix together all the ingredients for the sauce.

Take the pork out of the oven. Peel off the top sheet of foil. Brush the sauce all over the pork, including the sides and bottom.

Option 1: As soon as you take the pork out, turn up the oven temperature to the highest setting. If you have a “broil” option, choose it. Transfer the pork to a rack, put it back in the oven and cook for five to seven minutes. Take it out of the oven, brush it whatever remains of the sauce, put back in the oven and cook until nicely browned.

Option 2: About 10 minutes before you expect the pork to be done, fire up the grill — as hot as it can go. Grill the slab of meat, turning it over once one side is browned. When the meat appears to absorb the sauce, brush it again with the remainder of the sauce and continue grilling until nicely browned and charred.

To serve, arrange the sliced roasted and grilled pork ribs on a platter. They’re perfect with mashed potatoes or salad, or both.
