I was fed this (or something like it) by a fantastic Mexican lady a few months ago. I tried to piece together the recipe based on what she told me (in Spanish) was in it- but she gave me no amounts and no specific directions. My kind of cooking! All the ingredients can be adjusted, to taste. You can marinate this and cook it as a roast, or you can cook it in the crockpot with the marinade. If you start out as a roast, you can just throw leftovers in the crock for carnitas the next day (or freeze it and Crock it weeks later!).
