The pork is prepared for roasting like a prime rib of beef; you can follow the method here or have your butcher do it for you. For best results, start brining the pork five days before you plan to roast it.
03Remove pork from brine; discard brine. Rinse pork under cold running water for 5 minutes to reduce saltiness; pat dry with paper towels. Place pork on rack set over sheet of foil; let stand at room temperature 2 hours.
04Position rack in center of oven and preheat to 400°F. Place pork on rack in large roasting pan. Mix thyme and crushed peppercorns in small bowl; sprinkle mixture over pork. Roast until instant-read thermometer inserted into center of pork registers 140°F, about 1 hour. Remove from oven. Let roast rest 30 minutes (internal temperature of roast will increase 5 to 10 degrees).
05Remove kitchen string from roast. Cut meat into slices and serve.
