Combine Flour and Salt: In a large bowl, mix the flour and salt.
Cut in Butter: Add the chilled, diced butter and cut it into the flour using a pastry blender or two forks until the mixture resembles coarse crumbs.
Add Ice Water: Gradually add ice water, stirring until the dough just begins to clump together.
Form Dough and Chill: Gently knead the dough into a ball, wrap in plastic wrap, and refrigerate for at least an hour.
Roll Out and Fit into Pie Pan: On a floured surface, roll out the dough to fit a 9-inch pie plate. Transfer the dough to the pie plate and trim any excess from the edges.
