I will be entertaining a large group of people and want to cook around 15-20 pies. I am looking for some advice regarding the preparation of the dough. Specifically any ideas on how to form the dough ahead of time so I can limit the preparation at the party to just topping the pies. I have considered forming the dough individually and cooking briefly in the oven ahead of time. Or perhaps forming the dough and stacking between wax paper with flour. Can anyone give me any tips. Thanks.
