The pâte brisée recipe yields enough for 2 9-inch pies, so you can go ahead and freeze the second disk for future use. Without the whipped cream, the pie will keep for 2-3 days in the refrigerator. Once you put it all together it’s really best the day of although the second day is o.k., too.

Prepare the pie shell: Scatter flour across your work surface and roll out the dough to roughly an 11-inch round (don’t stress too much to get it exact). Lay it into a 9-inch glass or ceramic pie plate and trim any overhand that exceeds 1 inch from the rim. Fold under and crimp. Chill in the refrigerator until quite firm, about 15 minutes.
Preheat the oven to 425°. Line the crust with parchment paper and fill with dried beans to weigh down the shell when baking. Bake for about 15 minutes, until the crust is barely set. Remove the parchment and pie weights and cover the edge of the crust with strips of aluminum foil. Bake for about 15 minutes longer, until the crust is just set but not browned. If it starts to puff up, prick a few holes in it with a fork to release the air. Lower the oven temperature to 350°.
Make the custard filling: while the crust is cooking: In a medium saucepan, boil the cider until it’s reduced to 1/2 cup, about 10 minutes. Transfer to a bowl and let cool to room temperature. Whisk in 3/4 cup of the sugar, the sour cream, nutmeg and salt, then whisk in the eggs. Remove the foil strips momentarily, pour the custard into the pie shell, and replace the foil strips.
Bake the pie for 35 to 40 minutes, until the custard is set around the edge but the center is slightly jiggly. Let the pie cool completely.
Prepare the decorative apple slices: While the oven is still hot, slice the red apple very, very thinly. Use a mandolin or work slowly and carefully with a sharp knife. You don’t want your slices to be too thin so as to be transparent, but close. Spray your baking sheet with non-stick spray or very lightly brush the slices with vegetable oil. Bake them until the edges start to curl up and they start to turn golden, roughly 10 minutes.
In a medium bowl, using an electric mixer, beat the heavy cream with the remaining 1/4 cup of sugar and the cinnamon until firmly whipped. Spread gently on top of the pie, cut into wedges, adorn with baked apples and a dash of cinnamon on top, and serve. If you’re not serving right away, refrigerate until you are. If there’s pie leftover, refrigerate — it will be great the next day, too.
