Start by flouring your work surface, then take one of the discs of chilled dough out (keep the other in the fridge for now). As you roll it out, give the dough a quarter turn every few rolls until you have a nice circle about 12 inches wide. If you spot any cracks at the edges, smooth them out gently with your fingers. Keeping your work surface, rolling pin, and hands lightly dusted with flour will make this process smoother.
Now, carefully transfer the dough into a 9-inch pie dish, tucking it in neatly with your fingers for a smooth finish. If you'd like a thicker edge, I usually leave the excess dough around the edges instead of trimming it. Just fold that extra dough back over the edge and shape it into a nice thick rim—this can be done either before or after adding the top crust.
Add the filling into the crust.
Roll out the second pie crust just like you did with the bottom one. You have a couple of options here: you can simply place the crust over the filling for a classic double crust pie (make sure to cut a few slits in the top for ventilation) or get creative with a beautiful pie crust design, like a lattice or braided pattern. For the edges, you can crimp them with a fork or use your fingers to flute them.
To finish, brush the crust with an egg wash and, if you like, sprinkle some coarse sugar on top to add a delightful sweet crunch.
Preheat oven to 400℉. While it's heating, place your pie in the refrigerator. The colder the pie, the better it holds up its shape.
Bake for 20 minutes (with a baking sheet under it in case it bubbles over). At this point, add a pie crust shield or tin foil to protect the crust from burning. Lower the temp to 375℉, return to the oven, and bake for 35 more minutes.
Cool for at least 2 hours before serving to allow the filling to thicken up.
