In a bowl, combine flour and salt. Cut in lard until mixture resembles coarse crumbs. Sprinkle in water, a tablespoon at a time, until pastry holds together. Shape into a ball; chill for 30 minutes. On a lightly floured surface, roll dough to 1/8-in. thickness. Transfer to a 10-in. pie plate. Flute edges; fill and bake as pie recipe directs.
