Cut up your pork roast into 1 to 2 inch chunks (Don't trim the fat it will render in final part of cooking) and put it in a large pot. Add the cup of orange juice and your seasonings. Add enough water to just cover the meat (it's ok if it's not completely covered). Bring it to a simmer and let it simmer uncovered for 2 hours. I know you'll be tempted but DO NOT stir or touch the meat during these 2 hours. You should have enough water/juice in the pot that by the end of the 2 hours you will be down to about an inch or less of liquid. When you get to this point turn the heat up to medium high and chop and stir it around until the liquid evaporates and your pork is a mixture of something between chunks and shredded. I like to let it brown up a bit even. That's it, you're done! The best pork ever and the flavor is simple enough that you can do pretty much anything with the meat.
