Method1) Prep. Season the chuck roast with Kosher salt. If you can, give the salt 1 to 2 hours to be absorbed. The process of salting in advance is called dry brining. The rule of thumb is 1/2 teaspoon of kosher salt per pound of meat, but you can simply eyeball it by sprinkling on the same amount of salt you would use to season a steak if it was served to you unsalted. 2) Fire up. Prepare a smoker for indirect cooking. Alternatively, you can set up a charcoal grill for 2-zone cooking by placing a chimney full of pre-heated charcoal briquets on one side of the grill's charcoal grate in order to create direct and indirect cooking zones. Adjust the smoker or grill vents to bring the temperature to about 225°F and add 2 to 3 chunks of your favorite smoking wood to the charcoal for flavor. On a gas grill, adjust the temperature knobs so that one half of the grill is off and the other half is heated enough to maintain a temperature of approximately 225°F on the indirect side.3) Once the smoker or grill is ready, season the chuck roast with Big Bad Beef Rub.4) Cook. Place the chuck roast on the main cooking grate as far away from the heat source as possible. Set the lid on the grill with the top vent fully open and positioned directly above the chuck roast in order to force the smoke over and around the meat.5) Allow the chuck roast to smoke until it reaches an internal temperature of 160°F. Place the chuck roast on a double layer of aluminum foil, fold the sides of the foil up to create a boat, and pour the beef evenly broth over the meat. Tightly wrap the chuck roast in the foil and return to the smoker.6) Continue cooking the wrapped chuck roast until it reaches an internal temperature of 205°F.7) Serve. Remove the chuck roast from the smoker or grill and carefully open the foil to allow steam to escape. Alternatively you can store the wrapped chuck roast in a faux Cambro for up to two hours until ready to serve. Use two forks to shred the chuck roast just prior to serving.
