Mix sugar, flour, cinnamon, nutmeg and salt together and gently fold in apples. Place in skillet with 2 tablespoons butter. Cook on medium heat until apple slices are soft, but still keep their shape. Place mixture into a 9-inch pastry lined pie plate. Cover apples with top crust that has slits in it. Seal. Mix up small amount of milk and sugar and brush top of crust. Bake at 425 degrees for 40 to 50 minutes or until crust is brown and juice begins to bubble through slits. After removing from oven, sprinkle more granulated sugar on top.
