Before you begin, add ice to a cup of water so it gets nice and cold. Grate your butter into a bowl or cut it up into small pieces and place it in the fridge until you are ready to add it to your dough.
Place the flour, sugar, and salt into a mixing bowl and mix together with a fork or whisk. Add the cold butter and cut in using a pastry cutter or a fork. You can then use your hands to fully incorporate everything ensuring you have a coarse meal with some larger pieces of butter throughout.
Measure and add the ice-cold water to the dough and mix it in using a pastry cutter, a fork, or your hands. The dough will still be crumbly at this point, that is fine.
Dump the dough onto a lightly floured surface or a silicone mat. Create 2 equal-sized discs using your hands but do not press together too much, just lightly to quickly form 2 circles.
Wrap the discs tightly in plastic wrap and place them in the fridge for at least an hour to chill. If you only need one crust, you can place the other disc in a freezer bag and freeze for later.
When ready to roll out, remove the disc(s) from the fridge and allow it to sit at room temp for about 10 minutes. Roll the disc out on a lightly floured surface with a rolling pin, rotating and flipping as you go. Try not to handle the crust too much and allow it to rest for 5-10 minutes before shaping. Once you have the shape you need, place the crust in the fridge until ready to bake.
