With a fork, or in the Cuisinart with knife blade, mix:
4 c flour
1 Tbsp sugar
2 tsp salt
1 ¾ c shortening
In a measuring cup in the microwave, or in a small pan, heat gently until fairly hot:
1 egg beaten
1 Tbsp vinegar
½ c water
Blend with fork or pulse in Cuisinart until moistened/mixed. (I pulse the Cuisinart until it is clumped together).
Place on non-stick surface, or slightly floured surface, cut into quarters, shape each into a flat round, wrap with plastic wrap and chill at least 15 minutes or freeze until ready to roll out for pie or such.
Makes 2 double crust 9” pies and 1 9” shell.
