Heat oven to 375℉/190℃.
Combine flour and salt in the bowl of a stand mixer fitted with a pastry beater or a flat beater.
Turn on low briefly to mix.
Add butter.
Mix on low/medium-low until butter is completely coated in flour and broken down with some larger chunks remaining.
Add water.
Mix until it becomes dough, about 30 seconds.
Divide dough in half.
Wrap one half in plastic wrap, flatten into a disc, and refrigerate until needed.
Roll the other half of the dough into a ⅛ inch thick circle.
Fit into your pie dish, pressing gently to remove any air bubbles, but don't trim the edges.
Remove dough from refrigerator.
