Preheat oven to 350°f.

Open package of ham, place it in a 9x13 baking dish; coat top side with mustard and then sprinkle generously with brown sugar.

Pour enough milk into the pan to cover the ham.

Bake for 30-45 mins or until the top turns golden brown. It will be ugly. The resulting curds from the milk are slightly sweet with a bit of mustard coming through. It's fabulous when the curds and ham are eaten together.
