1Place all ingredients in Dutch oven or large, heavy saucepan. Add just enough water to cover meat. Bring to boil. Skim surface to remove any foam that rises to the top. Reduce heat to simmer. Cover and cook 1 hour.
2Remove lid. Increase heat to medium-high. Cook and stir until cooking liquid has evaporated, about 2 1/2 to 3 hours. Cook pork until golden brown and crispy, stirring occasionally (pork will shred easily). Remove from heat. Serve Carnitas in warm tortillas or use for sandwiches.
