Canadian Saskatoon Pie
Freezing Unbaked Pies:
Make the pie and then freeze it raw. Wrap the top of the pie with clear plastic wrap, then foil paper (this will prevent foil from sticking to pie crust when you remove it). Put the pie in a freezer bag; remove as much air as possible.
To cook, remove foil paper and plastic wrap. Cook frozen pie in oven preheated to 350 degrees F (180 degrees C) until the fruit is bubbling and the crust is golden, about 1 hour 20 minutes. It takes longer than a fresh pie.
Saskatoon berries may be called serviceberries in some markets.
