In a large bowl, whisk together flour, salt, and sugar. Add the cold butter cubes and use a pastry cutter or your fingertips to work it into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining.
Drizzle in ice water, one tablespoon at a time, mixing gently with a fork until the dough just comes together. Form the dough into a disk, wrap in plastic, and refrigerate for at least 1 hour.
After chilling, roll the dough on a lightly floured surface into a 12-inch circle. Transfer to a 9-inch pie dish, pressing gently into the bottom and sides. Trim excess dough, leaving a 1-inch overhang, then fold under and crimp decoratively. Return to refrigerator while preparing the filling.
Preheat your oven to 375°F (190°C). In a large bowl, whisk eggs until lightly beaten. Add pumpkin puree, heavy cream, brown sugar, cinnamon, ginger, nutmeg, cloves, salt, and vanilla extract. Whisk until smooth and well combined.
Pour the filling into the chilled pie crust. Bake for 20 minutes at 375°F, then reduce temperature to 350°F and continue baking for 35-40 minutes until the center is almost set but still slightly jiggly.
Place aluminum foil strips around the crust edges if they begin to brown too quickly.
Allow the pie to cool on a wire rack for at least 2 hours before serving. For the best flavor development and texture stabilization, cooling overnight in the refrigerator yields optimal results.
