Just like before, this was incredibly easy. After 3 hours, the pork was cooked but still holding together. After 4 hours, it was tender enough to shred. I substituted lemon juice for orange juice, because I had an extra lemon on hand. I tried it without reducing the braising liquid, and it was effectively tasteless. Reduce the liquid to add the lovely flavor back.
This worked well as soft tacos for almost a week. A bit of lettuce, cheese, and sour cream turned it into something reminiscent of Taco Bell, if they'd ever serve pork (and I mean that in the best possible way).
All together, my experiment with a pork shoulder turned out great, and I'm glad to have another thing to look out for when I'm perusing the local grocery store.
