Yes. After you’ve brined the pork butt or shoulder, rinsed it, dried it, and rubbed it with spices, toss it in the slow cooker along with the ale, onion, orange, and pineapple and cook, covered the entire time, until the pork is tender and falls apart. This could take 6 to 12 hours on low, or you could start it on high for 2 hours, then switch it to low for the final 4 hours of cooking. Use tongs to transfer the pork to a plate, leaving the cooking liquid in the slow cooker. Then use a couple of forks to gently pull apart the meat. Squeeze the juice from the remaining orange quarter over the shredded pork and pile it onto a platter. If desired, strain the cooking liquid from the slow cooker and dribble some of it over the shredded pork to moisten it.
