In a bowl, whisk together flour, salt, and sugar.
Cut in cold butter using a pastry blender or fork until the mixture looks like coarse crumbs.
Add ice water, one tablespoon at a time, until dough holds together when pinched.
Shape into a disk, wrap in plastic, and chill for 30 minutes.
Roll out the dough on a floured surface, fit it into your pie dish, and crimp the edges.
Chill again for 15 minutes. Then line with parchment and fill with pie weights.
Blind bake at 375°F (190°C) for 10 minutes. Remove weights and bake another 5 minutes.
