Cut pork into 2-inchmcubes, add to a large pot with the juice, water, and salt. Bring to a boil and then simmer uncovered on low for 2 hours. Do not touch the meat.
After 2 hours, turn heat up to medium high, and continue to cook until all the liquid has evaporated and the pork fat has rendered (about 45 minutes). Stir a few times, to keep pork from sticking to bottom of pan.
When pork has browned on both sides, it’s ready (there will be liquid fat in the pan). Serve either cubed or shredded (pork will be tender enough that just touching it will cause it to fall apart) with tortillas and green chile creamy avocado salsa.
Notes
The key to this recipe is that the meat has fat, so don’t trim it! If there’s not enough fat on the meat the recipe will turn out too dry. Whether to shred the meat like pulled pork or leave it in cubes I think is determined by what you’re used to eating. Texas isn’t a pulled-pork state so the texture isn’t as familiar as nicely done chunks. Likewise, I think the brilliance of this recipe lies in its simplicity. You can add as many different spices, herbs and aromatics as you like—but if you have good-tasting, happy pork why not let its flavor shine with just a bit of salt? Ultimately, however, making carnitas is a highly personal affair and so make them as they best suit you!
