Sift the flour and salt together into a large mixing bowl. Cut in the shortening thoroughly with a fork or pastry cutter. Stir in the water, starting with 4 tablespoons and adding up to a tablespoon more if the dough seems too dry.
Bake in the preheated oven for 6-8 minutes, or until the dough is firm and lightly golden. Cool in the pan on a wire rack for at least 5 minutes before removing from the pan to cool on the wire rack completely.
