Trim your pork as needed to remove the big pieces of fat. The rest will mostly melt away and you want some for flavor. Place the olive oil, cumin, oregano, and paprika in the bottom of your crock pot. Add the pork and roll it in the mixture until it's nicely coated in the spices on all sides.
Chop your onion and mince your garlic, then add to the top of your pork. Add the stock, then cut your orange in half. Squeeze the orange into the crock pot for the juice, then go ahead and toss the halves into the crock pot, as well.
1 onion, 6 cloves garlic, 1/2 cup stock, 1 orange
Cook on low for 6 to 8 hours. When it's done, the meat will be already almost falling apart in the crock pot, and the oranges will look cooked. Fish out the orange halves.
Using tongs or forks, shred the pork right in your crock pot. Don't worry about getting it perfect. You just want it most of the way shredded.
In a heavy pan, melt your fat and add the pork in batches, frying until crispy and browned. You'll want to stir it occasionally to ensure all the edges get a little browned.
Serve immediately over rice, in burritos, in tamales, and more.
Although I fried the pork at the end, this would also work to broil it on a baking sheet with some of the liquid. You would just need to turn it after a couple of minutes and broil it in total for around 5 minutes. Next time around, I'm going this route to save time.
