Grilled Pork Roast with Pepper Jelly Glaze

Place pork in large self-sealing plastic bag. Heat marinade ingredients together until jelly melts; pour over pork in bag. Seal bag, refrigerate 12 to 24 hours. Remove pork from marinade (discarding remaining marinade). Place pork roast on medium-hot grill over drip pan, close grill hood. Grill pork for about 1 1/4 hours, until meat thermometer inserted in center reads 150°F (65°C). Stir together glaze ingredients; coat roast with jelly glaze. Grill for 10 minutes more, bringing roast to an internal temperature of 160°F (70°C). Let roast rest 10 to 15 minutes before slicing to serve.
