Ingredients

One 4 pound pork shoulder roast, preferably Boston butt, boneless or bone-in

5 to 6 cups of wood chips, hickory, oak, apple, or other fruit wood

2 Tbsp brown sugar, packed

2 Tbsp white sugar

2 Tbsp paprika

1 Tbsp kosher salt

1 1/2 teaspoons ground cumin

1 1/2 teaspoons garlic powder

1 1/2 teaspoons chipotle chile powder

1 1/2 teaspoons black pepper

1 Tbsp salt

1 Tbsp finely ground black pepper

1 Tbsp garlic powder

1 Tbsp onion powder

1 teaspoon cayenne

1 Tbsp dried oregano

1 teaspoon dry rosemary

1/2 teaspoon dry sage

1/4 teaspoon sugar

Directions

Prepare the rub. Mix all the ingredients for the rub together, breaking up any clumps. Taste the rub as you make it and see if you like the taste, adjust accordingly. Rub the roast with the rub. Unwrap the pork roast and place it on its butcher paper or in a roasting pan, something that can catch the rub. With your hands work the rub mixture into the pork shoulder all over, including inside any crevasses you may find in a boneless roast where the bone had been. Be generous with the amount of rub. Rewrap it in the butcher paper or wrap it in plastic and place it in a pan , and refrigerate it overnight.

Soak the wood chips. Take 3 or 4 large handfuls of wood chips and place them in a bowl and cover them with water to soak them overnight . I think it helps to have a mix of sizes, from small chips to larger chunks. The smaller chips will get smoking more quickly, but will burn out more quickly too. The larger chunks will take longer to catch, but last well past when the smaller chips have burned themselves out.

Bring the chilled roast to room temp. 1 to 2 hours before you start the barbecue, take the pork out of the refrigerator to come to room temperature. Now, if you forget to do this, which I have done, you can still go ahead and BBQ it. You'll likely be finishing it in the oven anyway. It will just take a bit longer to cook. Prepare your grill. Remove one of the grill grates. This will be your "hot" side, where the wood chips will go. The other side of the grill will be the "cool" side, and where the meat will be, away from direct heat. Depending on the structure of your grill, you may want to remove the "flavor bar", the thin metal piece with lots of holes in it that sits over the burner. The wood chips will smoke more easily if they lay in a container directly on the burner.

If there is room on your grill, place a small aluminum tray of water on the grill to help moderate the heat and help keep the roast from getting too dry. A good place to place this is on an upper rack if you grill has one. Get the grill smoking. Create a double layered aluminum foil boat with a handful or two of damp wood chips in it. Place the boat directly on the burner on the "hot" side of the grill if you can . Turn the grill on to medium flame, cover the grill and let it heat up until the the wood chips start smoking. You'll either see smoke coming out of the grill, or if you raise the lid, you'll see smoke coming out of the wood chip boat. You should see and smell the smoke. You'll be replenishing the wood chips periodically for the next several hours so put more dry chips into water to soak if needed.

Once the grill is smoking, place the roast on the grill grates on the cool side of the grill, away from direct heat. If your grill has a hot spot, position the roast away from it. If there is a fatty side to the meat, put that side facing up; the fat will render over time and baste the pork. Cover the grill, lower the flame, and let the cooking begin. The temperature you want to maintain ideally is 225 degrees F. Try to keep it close to that temperature, within a range of 210 degrees F to 240 degrees F. If the temperature goes too high, the roast may dry out. If it's too low, it will take forever to cook. Maintain the smoke and the 225 degrees F temperature. This is the tricky part. You will want to maintain smoke in the grill for at least 4 hours . You will also want to maintain a cooking temperature of around 225 degrees . So, you have to check the grill! Check if the temperature is being maintained between 210 degrees F and 240 degrees F, and check to make sure the chips are still producing smoke, every half hour. About once an hour you will likely need to replenish the chip boat with more wood chips. Resist the temptation to open the grill more than once an hour. Every time you open the grill the inside temperature drops and you increase your overall cooking time. I found the best way to check the temperature, since I don't have a gauge in the grill itself, is to put an instant read meat thermometer into an opening in the hood on the meat side of the grill, and just keep checking it. Make sure sensor tip of the probe is not touching the meat itself. You want to avoid opening up the hood too often, because every time you do that, you lose heat. Of course, if your gas grill gets too hot, opening the hood can cool it down quickly. Expect a minimum cooking time, if you have been diligent at maintaining a 225 degrees F, of 90 minutes per pound. So if you are cooking a 4 pound roast, total cooking time will be at least 6 hours . An 8 pound roast will take at least 12 hours of cooking time. If you want to cook 8 pounds of pork shoulder more quickly, I recommend starting with two 4 pound roasts, spaced on the grill a few inches apart, which will cook in just a little more time than an 8 pound roast.

After 2 or 3 hours, during one of your hourly opening of the grill to refresh the wood chips, reposition the roast so that the side that was closest to the heat is now furthest from the heat. Test internal temperature of meat.

You can eat it at 165 degrees F, but if you are making pulled pork the meat needs to be ideally 195 degrees F.

When the meat reaches 195 degrees F, remove it from the heat, tent it loosely with foil over a cutting board and let it rest for at least 30 minutes, and preferably 1 hour. If after 6 hours of cooking, if the meat hasn't reached 195 degrees internal temp , my recommendation is to remove it from the grill and finish in the oven. To finish in the oven, wrap the roast in aluminum foil to help prevent it from drying out in the oven, and place it in a roasting pan, in a 300 degrees F oven. Cook until the internal temperature of the roast reaches 195 degrees F. If your starting internal meat temperature is 150 degrees F or so, this can take anywhere from an hour to two hours. When it reaches temperature, remove the roast from the oven and let rest for at least 30 minutes, up to an hour. Pull the pork. Pull the pork with 2 forks. Only now do you add any barbecue sauce to the meat. Taste it first! It might not need sauce at all, and if it does, add only a little at a time. One of the biggest sins of barbecue is to over-sauce perfectly good meat. Serve on a bun with or without sauce, and with or without coleslaw. Also great with grilled or raw pineapple.
