Preheat oven to 325 degrees F.
First, make the spice rub. Whisk together the paprika
, kosher salt, black pepper, garlic powder, chili powder, mustard
powder and cayenne. Massage the spice rub into the pork butt, coating on all sides.
Place the rubbed pork in a large Dutch oven; add beer, cider vinegar and liquid smoke. Cover and cook for approximately 3 hours, basting occasionally, until the pork easily falls apart. Remove the pork to a large cutting board while still hot. Cut off excess fat and carefully shred
the meat; it is harder to pull once it has cooled. (I either wear heavy-duty rubber gloves on my hands or use my new "bear paws," but two large forks would work, too.) Place the shredded pork back into the Dutch oven
and toss with its cooking juices. Cover and set aside until moving forward with the recipe. Yield: 1 1/2 to 2 pounds pulled pork, depending on the amount of fat and bone on the cut.
To reheat, cook the barbecue (in its Dutch oven) over medium-low heat until warm. If you want crispier shredded pork (more like your favorite barbecue house), reheat it on the stovetop first, then spread it on a sheet pan
and pop it under the broiler for a few minutes, watching carefully so it does not burn.
