Place sifted Carbalose flour into a mixing bowl.
Cut the cold butter into small pea sized cubes.
Using a pastry blender, cut the butter into the flour, making sure you get the sides of the bowl.
Sprinkle 1 tbsp of cold water over the mixture, repeating as needed.
Work with a pastry blender until the dough is a crumble, about half the size of peas.
*When the dough is ready it sticks together when pinched between your fingers.
Form the dough into a ball and wrap it in plastic wrap.
Refrigerate for at least 20 minutes before rolling. (you can refrigerate overnight)
When you are ready to roll the crust, remove it from the refrigerator and let it sit for a few minutes at room temperature.
Roll on a lightly floured surface or between two pieces of parchment or waxed paper.
Carefully lift the rolled crust with a rolling pin (draped over it) or with the paper and place it over a pie plate.
Flute or fold the edges as desired.
