2 C. all-purpose flour
1 tsp. salt
4 to 5 Tabsp. cold water
(I add about 1 tablespoon of vinegar to the cold water)
Mix shortening into flour and salt until particles are the size of small peas. Sprinkle in water, 1 tablespoon at a time, tossing with fork until all flour is moistened and pastry almost cleans the side of the bowl. Gather pastry into a ball; shape into flattened round on light floured board.
For 2 crust pie, divide pastry in half and form 2 rounds.
