Step 1: Butterfly the pork loin: Using a very sharp knife, cut the roast almost in half lengthwise through one side, stopping about 1/2 inch from the opposite side. Open the roast up as you would a book.
Step 2: Spread the inside of the pork loin with mustard, then sprinkle with brown sugar. Distribute the baked beans on top and drizzle with bourbon. Carefully fold the roast back together (like closing a book).
Step 3: Cut four 12-inch pieces of butcher’s string. Position the pieces of string on the work surface so that they are parallel and roughly 2 inches apart. Place 2 slices of bacon across the strings so that they are parallel to each other and perpendicular to and in the center of the strings. Set the roast on top of the bacon, positioning its long side parallel to the bacon. Place 2 slices of bacon on top of the roast. Press the remaining 2 slices against the long sides of the roast. Tie each piece of string together around the roast so that they hold the slices of bacon against it. (When you finish, the roast will be encased in bacon).
Step 4: Set up the grill for indirect grilling and preheat to medium-high (400 degrees). If using a charcoal grill, place a large drip pan in the center, preheat the grill to medium, then add the wood chips or chunks to the coals. If using a gas grill, place all of the wood chips or chunks in the smoker box or in a smoker pouch and run the grill on high until you see smoke, then reduce the heat to medium.
Step 6: When ready to cook, place the pork roast on the hot grate, over the drip pan and away from the heat and cover the grill. Cook the roast until cooked through, about 1 to 1-1/2 hours. (If you are using a charcoal grill, replenish the coals as needed.) The last 15 minutes, start basting the roast with Smoke Wrangler’s Barbecue Sauce, if using. Baste once or twice more. To test for doneness, insert an instant-read meat thermometer into the side of the roast. The internal temperature should be 145 to 155 degrees.
Step 7: Transfer the cooked roast to a cutting board and let it rest for 5 minutes, then remove and discard the strings. Slice the roast crosswise with a serrated or an electric knife. Serve the remaining barbecue sauce and additional baked beans on the side.
