Reduce the heat slightly and add the milk to the pan or casserole very, very slowly so it doesn’t bubble up too much. Gradually bring it to a gentle simmer and partially cover the pan. Let the pork cook like this for 2 hours, or until the juices run clear when pierced with a skewer. The pork will be tender but not fall-apart tender and the milk will turn yogurt-like and clumpy and may brown somewhat.☞ TESTER TIP: The milk sauce won't look pretty. But just wait until you taste it.
