Add flour, sugar and salt to a food processor and pulse to combine
Cut your cold butter into cubes and add to the flour mixture
Give that a few pulses to break up the butter, just a little
Begin adding your ice water, 2 tablespoons at a time and pulsing in between. Keep adding ice water and pulsing until the dough starts to come together (you may not need all of the water).
NOTE: You're not looking for a hard dough. When it's ready, the dough may look a little crumbly, but you'll be able to pinch some dough with your fingers and have it stick togetherOnce the dough is ready, remove it from your processor and divide it into two equals. Using your hands, form each portion into round disks. Wrap each disk tightly with plastic wrap and either place them in the fridge, if you'll be using it soon, or put the wrapped dough into a freezer bag to freeze for later use.
