In a small bowl combine brown sugar, salt, chili powder, dry mustard, garlic powder, cayenne pepper, and pepper. Mix well. Place four Kansas City Strip Steaks on each of two pieces of heavy-duty aluminum foil (shiny side down) and generously coat with rub on both sides. Lightly seal foil packets and place on a cookie sheet. Chill for 1 hour. Meanwhile, in medium bowl whisk to combine jelly, vodka, broth, vinegar, sorghum, Worcestershire sauce, mustard, and hot sauce. Open one end of each packet and pour ½ of liquid into each packet. Tilt baking sheet to allow liquid to distribute evenly. Prepare medium-hot coals for indirect grilling. Grill packets for 1 ½ hours. When meat is tender, remove packets from grill, but keep wrapped in foil. Five minutes prior to serving, remove steaks from packets and place directly on grill to caramelize glaze. Brush with braising liquid and serve.
