To make crust, in a large bowl mix the flour, sugar and salt. Cut in the chilled butter and shortening with a fork or pastry blender until crumbs form. Add the water, 2 T. at a time, until the dough holds together. Form dough into a ball and pat flat, making sure dough is not too dry and do not handle too much or it will get tough. Roll out onto floured surface with floured rolling pin. Transfer to a 10” pie pan and cut off all but ½ around and flute; prick bottom with fork.
