Combine the all-purpose flour, granulated sugar, and salt in a large mixing bowl.
Add the chilled and cubed unsalted butter to the bowl.
Using a pastry cutter or your hands, work the butter into the flour mixture until it resembles coarse crumbs.
Gradually add the ice-cold water and mix until the dough comes together.
Form the dough into a disc, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Making The Filling:
Preheat your oven to 375°F (190°C).
In a separate bowl, combine the mashed Candy Roaster Squash, heavy cream, brown sugar, granulated sugar, eggs, vanilla extract, ground cinnamon, ground ginger, ground nutmeg, and salt.
Mix the ingredients thoroughly until well combined.
Assembling And Baking The Pie:
Roll out the chilled dough on a floured surface to fit a 9-inch pie dish.
Gently place the rolled-out dough into the pie dish, pressing it against the bottom and sides.
Pour the prepared filling into the pie crust.
Baking The Pie:
Place the pie in the preheated oven and bake for 45 to 50 minutes or until the filling is set and the crust turns golden brown.
Once baked, remove the pie from the oven and let it cool on a wire rack.
