Remove the pork from the refrigerator at least 2 hours before putting it on the smoker. The meat should be at or approaching room temperature before you start the smoke. This is done to save cooking time, allow for even cooking, and smoke penetrates the meat more easily at warmer temperatures.
Start up your smoker. If using charcoal, make sure you have enough coals for 8 straight hours. If you have a diffusion plate in your smoker, set it up with some water or apple juice. Do not allow for direct-heat cooking.
20 minutes before starting the smoke, soak the wood chips in hot water. This will allow for a slower “smolder” of the wood. Electric smokers – you don’t need to do this step with pellets or pucks.
Stabilize/set the temperature of the smoker to 225-235 F. Add the smoking chips, and then add the meat to the grill… fat side up. Close the lid on the smoker as soon as possible to keep the smoke in. Tip: use a digital thermometer on the grill grate to monitor temperatures inside your smoker.
While maintaining 225-235 F., continue to smoke the pork for 4 hours. Roughly every 45 minutes or so, spritz the meat with the juice. Low and slow is the key… no excessive peeking!
Once 4 hours has elapsed, check on the pork. You should have a nice dark bark (crust) on the outside with a reddish hue. If you want more bark, continue to smoke for a bit more. The key here is to smoke to colour… not a temperature. For reference, the internal temperature will be around 140-160 F. depending on size.
Once you are happy with the colour, remove the pork from the smoker temporarily and place it on top of 4 large sheets of aluminum foil. Wrap the pork along with the garlic in the aluminum foil as tightly as you can. No gaps. Ensure that there is no chance for steam or juices to escape. You can also substitute butcher paper in lieu of aluminum foil.
Adjust the temperature of the smoker to 330-350 F. Place the wrapped pork back on to the grill and close the lid. For charcoal people, this is a good time to add more charcoal.
Continue to cook the pork for another 3 hours minimum. At this point the meat is steaming in its own juices. At roughly the 3-hour mark, check the internal temperature of the meat using a digital thermometer. Poke the thermometer through the foil… do not unwrap. You are looking for an internal temperature of 205 F., and there should be very little resistance when pushing the thermometer in (like hot butter). If the temperature is not at or slightly above 205 F., continue to cook the meat until it does.
Once at temperature, remove the meat from the smoker and leave it to sit for 20 minutes on a cutting board, still wrapped in foil. This allows the muscle fibers of the meat to relax and re-soak up the juices.
Unwrap the pork and pull it. An easy way to do this is by using a pair of tongs or 2 forks to shred the meat. It should shred easily into long strands. Remove any excess fat or cartilage that may be in the meat. Mix thoroughly so that the bark outside and center meat is distributed evenly along with the garlic.
At this point you can serve the meat as-is (dry), add the BBQ sauce to the mix, or try some combination of them both.
Serve! Best served the day of the smoke on a fresh Kaiser roll, a pretzel bun, or as a main. Recommended side dishes are potato salad, garden salad, corn on the cob, or a vegetable medley.
