Using the dough blade or paddle attachment, combine the flour, sugar and salt in the bowl of a food processor or stand mixer. Pulse to ensure the mixture is evenly distributed.

Add in the cubed butter and pulse a few times to break up the chunks, but there will still be some pieces of butter unblended. Add in the cold water and pulse until combined; it should form a rough dough.

Transfer the mixture onto a floured work surface and press all the dough together into a pile. Using two hands press down on the top of the mixture. Fold the dough into itself until most of the butter dissolves into the flour.

Form two dough balls, and flatten each into 1-inch thick discs using your hands. Wrap each tightly in plastic, and store in the fridge for 4 hours before using in a pie recipe.
