Combine the flour and salt in a bowl.
Cut in the cold butter until the mixture resembles coarse crumbs.
Gradually add ice water and mix until the dough comes together. Form it into a disk, wrap it in plastic, and chill for at least 30 minutes.
Roll out the pie crust on a floured surface and transfer it to a pie dish. Trim any excess and crimp the edges.
In a separate bowl, whisk together the pureed pumpkin, evaporated milk, eggs, sugar, spices, salt, and vanilla extract.
Pour the pumpkin filling into the pie crust and smooth the top.
Bake at 425°F (220°C) for 15 minutes, then reduce the heat to 350°F (175°C) and continue baking for 40-50 minutes, or until the center is set.
Allow the pie to cool completely before serving
