Preheat oven to 425°F.
Prepare the pie crust and line a 9-inch pie plate with it, crimping the edges. Set in the fridge while preparing the filling.
1 [unbaked pie crust]
In a large bowl, whisk together the pumpkin, sugars, eggs and vanilla.
1 (15-ounce) can pumpkin puree, 1/2 cup granulated sugar, 1/2 cup light brown sugar, 3 large eggs, 1 teaspoon pure vanilla extract
Add cornstarch, cinnamon, ginger, salt, cloves, nutmeg, and allspice, whisking well to combine. Stir in evaporated milk, then pour into the prepared pie crust.
1 Tablespoon cornstarch, 1 1/2 teaspoons ground cinnamon, 1/2 teaspoon ground ginger, 1/2 teaspoon salt, 1/4 teaspoon ground cloves, 1/4 teaspoon ground nutmeg, 1/8 teaspoon ground allspice, 1 (12-ounce) can evaporated milk
Bake at 425°F for 15 minutes, then reduce the heat to 350°F and continue to bake for another 40-50 minutes until the edges of the pie are set and the center just barely wobbles.
Allow the pie to cool completely for 3-4 hours, then refrigerate until ready to serve.
