Add 2/3 (about 8 oz) of the flour to the bowl of food processor. Add in the sugar and salt and pulse to combine. Lay out the cold butter evenly over the surface of the flour. Begin pulsing the flour and butter together. Continue until the flour and butter are completely combined and there is no dry flour in the processor and the dough has clumped up, be patient. You will know when the dough has formed and will be a big clump in the processor.
Spread out the dough with a rubber spatula and then sprinkle the remaining flour over the top. Pulse just few times, 5-6 quick pulses, to break up the dough. Transfer the dough to a large bowl.
Sprinkle the water over the dough and use the rubber spatula to fold and mix the water into the dough. Once the water is mixed in and the dough has become a cohesive ball, turn out the dough onto a well floured surface. Flour hands and fold and press the dough a few times by hand so that it makes a nice, smooth ball that can be shaped into a disc. Divide the dough in half and shape each half into a disc. Wrap each disc in plastic wrap and let it rest in the refrigerator for at least 2 hours and up to 3 days.
After the dough has rested, use it in any recipe calling for one or two 9-inch pie crust
When you are ready to roll make sure you let the dough sit out until it's pliable. Refrigerated dough is too cold to roll and will crack as you work.
