Measure flour and salt into a large mixing bowl. Reserve 1/3 cup mixture and put it in a small bowl.
Add shortening to large bowl and with your hands rub the flour into the shortening until texture is that of cornmeal.
Using your finger, mix the water with the reserved flour mixture in the small bowl to make a paste and add it immediately to the flour-shortening mixture in the large bowl.
Mix it in thoroughly and form dough into a ball. Divide dough into two parts and roll each out between saran wrap.
Lay the crust loosely over the pie pan and lift edges of crust to fit it into the pan. Trim off excess crust, fold under the over-hang to edge of pan and flute.
Prick the crust around the sides and over the bottom.
Bake for 10-12 minutes, until light brown at 375 degrees
