Place the flour, confectioner's sugar, and salt into a large baking bowl.

Add the butter and using your finger tips, rub the butter and flour together until it resembles breadcrumbs. Do this very quickly to prevent the butter from softening.

Add the water and egg mixture until the mixture sticks together.

If the mixture is a little dry add a few drops of water.

Now proceed to what the French call the "fraisage", but as the dough will be difficult to handle, you can use a piece of plastic wrap to place the dough on. Then push the dough away from you with the heal of your hands until it is smooth.

Wrap in the plastic and place in the refrigerator for 2 hours.
