Whisk flour, sugar, and salt together in a medium bowl.
Using a pastry cutter or two butter knives, cut in butter until the size of large grains of sand.
Add half of the water and flake with a fork until flour mixture starts coming together. Add a little more water and mush together with your hands just until combined and you can bring into a ball. Do not over handle your dough.
Turn on a floured board, shape into a ball and flatten into a disk.
Cover disk completely in flour. Place dough in the refrigerator.
Preheat oven to 390°
