This is a recipe in progress, but it's easy and reasonably tasty as is. Serve with any number of sauces.
Cut the pork into long chunks
Mix together all the sauce ingredients and marinate the meat for several hours or overnight.
Preheat the oven to 375
Boil some water (I used a tea kettle)
Line a large roasting pan with tin foil and put cake racks over it. Lay the meat on the racks, put it in the oven, and then carefully add the boiling water to the pan.
Roast for an hour or more, adding water if it cooks away. Turn meat once during cooking. The outside of the meat should be dark and glossy.
Slice and serve hot or cold.
