2 c. flour
1 tsp. salt
1 well-beaten egg
1/4 c. plus 1 tsp. cold water

Cut shortening into flour and salt mixture until it resembles corn meal. Combine beaten egg, water, and vinegar; add all at once to flour mixture. Stir with flour until blended; do not over stir. The mixture should be crumbly. Press together with hands to form a ball. Let stand 5 minutes. Split into 2 pieces. Roll on board to 1/8 inch thick. Fill pie. Bake at 425 degrees for 30 minutes.
