Add 1 cup of milk (add the milk slowly so it doesn't boil over). Allow the milk to come to a simmer for 20 to 30 minutes, then turn the heat down to low and cover the pot with the lid slightly ajar. Cook at a very lazy simmer about 1 hour, turning the meat from time to time, until the milk has thickened, through evaporation, into a nut-brown sauce. When the milk reaches this stage, add 1 more cup of milk and let simmer for about 10 minutes; then cover the pot, putting the lid on tightly. Check and turn the pork from time to time.
After 30 minutes, set the lid slightly ajar. Continue to cook at low heat, and when you see there is no more liquid milk in the pot, add the other 1/2 cup of milk. Continue cooking until the meat feels tender when prodded with a fork and all the milk has coagulated into nut-brown clusters.
Altogether it will take between 2 1/2 and 3 hours. If, before the meat is fully cooked, you find that the liquid in the pot has evaporated, add another 1/2 cup of milk. Transfer the meat to a cutting board. Let it settle for a few minutes, then cut into slices about 3/8-inch thick or slightly less, and arrange them on a serving platter. Tip the pot and spoon off most of the fat, being careful to leave behind all the coagulated milk clusters. Add 2 or 3 tablespoons of water, and boil away the water over high heat while using the wooden spoon to scrape loose cooking residues from the bottom and sides of the pot. Spoon all the pan juices over the pork and serve immediately.
