Use whole milk. Put into refrigerator to speed cooling, about 15 min. Stir in nutmeg just before spooning into pie. Take chilled pie crust from refrigerator. Gently put in cooled, cooked apple pieces.
Dot apples with cranberries evenly around the top.
Pour cooled custard on top of apples. Evenly distribute custard with a wooden spoon. Bake in a 400 degree oven for 25-30 min. Watch so crust does not burn. The custard on top should have a nice dark brown color.
