Use your fingers to press the dough together to form a big dough ball. It should be dry and crumbly but still hold together. If you are having issues with it staying together add ice cold water a tablespoon at a time. Do not add too much water you don't want sticky dough
On a clean work surface, cut the dough in half and form each half into a disk. Cover the disks with plastic wrap and place in the fridge for at least 1 hour before rolling out. You can keep it in the fridge overnight and use it the next day if you want to prepare ahead.
When ready to use crusts, remove from the fridge and on a clean light floured surface and with a lightly floured rolling pin, roll out the dough until a very rough circle is rolled out. It should be about 13 inches wide. Place this into a clean 9 inch pie pan.
Roll out the second circle so it is about 12 inches wide and cut it into 10 strips of dough (5 horizontal, 5 vertical).
