Make Pie Doug.
Refrigerate pie dough for 30 minutes.
Take pie dough out 10 minutes before rolling out.

Roll out into circle larger than pie pan. Use fork to jab holes on bottom;

You can do what I do and use cookie cutters to make fun tops. Or you can do a lattice top.
Here is a great tool from Amazon, which is adjustable.
Bake at 350 for 90 minutes. Check your pie at 60 minutes. If it's browning too much on top, place foil over it.
