Preheat oven to 400.
In a small skillet place 1 stick butter over medium heat. Allow butter to melt. Stir the butter frequently. It will start to look foamy and you should see brown bits forming and it will smell nutty. Stay right with it, and be careful it doesn't burn.
After butter is browned, place in the freezer to harden.
In a Nutri- Bullet, place pecans and pulse them a couple times to crush them into small pieces.
In a medium bowl with a wooden spoon mix flour, salt, sugar, and pecans.
Remove the hardened brown butter from the freezer and cut into flour mixture with a pastry cutter or fork until butter is pea-size.
Add water a tablespoon at a time stirring after each tablespoon. Continue to add until the dough just comes together.
Turn dough into a lightly floured surface and roll with a rolling pin until it's about a ¼ inch thick.
Place into the pie dish removing any excess and making edges look nice. Set in fridge to stay cool while you make the filling.
