Mix 12oz sanding sugar and 0.5oz cinnamon together and reserve. Remove pie lid from freezer and let come to room temperature. Mix together 1 pound 12oz apple filling and 4oz cranberries. Fill shell with prepared filling. Slice pie lid into 0.5 inch strips, and into 1.5 inch strips and place in lattice pattern on top of prepared shell. Trim edges, egg wash, and sprinkle liberally with reserved cinnamon & sugar mixture. Bake at 350F until dough strips are golden brown.
To make egg wash, use a ratio of 2:1 whole eggs: water. For example, for every pound of eggs used, add 8oz water. Mix together and add a pinch of salt if desired.
