Prepare the Pie Crust:
In a food processor, combine the flour and salt. Add the chilled butter cubes and pulse until the mixture resembles coarse crumbs. Gradually add ice water until the dough comes together. Knead the dough, form a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Preheat the Oven:
Preheat your oven to 425°F (220°C).
Make the Pumpkin Filling:
In a mixing bowl, whisk together the Jarrahdale pumpkin puree, heavy cream, brown sugar, cinnamon, ginger, nutmeg, allspice, vanilla extract, eggs, and salt until smooth and well-combined.
Roll Out the Dough:
Roll the chilled dough into a 12-inch circle on a lightly floured surface. Place it into a 9-inch pie dish, pressing it into the sides and trimming any excess dough. Crimp the edges for a decorative finish and prick the bottom with a fork to prevent bubbling.
Assemble the Pie:
Pour the prepared pumpkin filling into the pie crust, smoothing it evenly with a spatula.
Bake the Pie:
Bake the pie at 425°F (220°C) for 15 minutes. Reduce the temperature to 350°F (175°C) and continue baking for 45-50 minutes, or until the filling is set and the center is firm.
Cool the Pie:
Allow the pie to cool completely on a wire rack before serving. This ensures the filling sets properly.
Serve:
Serve the pie with whipped cream, vanilla ice cream, or a drizzle of caramel sauce.
