1️⃣ Preheat oven to 375°F (190°C).
2️⃣ Make the crust: In a large bowl, whisk flour, salt, and sugar. Cut in butter with a pastry cutter or your fingers until coarse crumbs form. Stir in ice water, 1 tbsp at a time, just until dough comes together. Shape into a disk, wrap, and chill for 30 minutes.
3️⃣ Roll out chilled dough on a floured surface and fit into a 9-inch pie dish. Trim & crimp edges.
4️⃣ Line with parchment, fill with pie weights or beans, and bake for 10 minutes. Remove weights and bake 5 more minutes.
5️⃣ Make the filling: In a medium bowl, whisk pumpkin, brown sugar, eggs, evaporated milk, salt, and spices until smooth.
6️⃣ Pour filling into pre-baked crust and bake 45–55 minutes, until filling is just set but still slightly wobbly in the center.
7️⃣ Cool completely on a wire rack, then chill for at least 2 hours before slicing.
