Cook for 10-12 hours or until the meat is falling apart.
Using two forks, shred the pork and leave it in the juice in the crockpot. Pull out the orange peels.
OPTIONAL: Place the pork on a baking sheet and stick it under the broiler for a few minutes. You can also sauté it in a skillet with a little oil in batches. Then place it back in the juices in the crockpot to serve.
We like to serve ours with warmed corn tortillas, cilantro, diced red onions and cotija or queso fresco and sometimes a little avocado.
