Pour into one measuring cup (but do't stir together): 1/3 cup cooking (salad) oil such as Wesson
Then oour all at once into flour.
Stir until mixed. Press with hands into smooth ball. Flatten slightly. Place between 2 sheets of waxed paper (12-inch square). Roll out gently until circle reaches edge of paper.
(waxed paper will not slip while rolling pastry if table top under paper is slightly damp.)
Peel off top paper. If dough tears, mend without moistening by pressing edges together...or by pressing a scrap of pastry lightly over tear. Lift paper and pastry by top corners; they will cling together.
Place paper-side-up in 9-inch pie pan. Carefully peel off paper.Gently ease and fit pastry into pan. Build up fluted edge.
