Fool Proof Pie Crust

My mom and I felt a little bad about tossing Grandma's crust recipe and switching to this one but it's a keeper. An old World Education colleague, Kim, brought in an apple pie to work one day. It was the best crust I've ever had. I was surprised by the vinegar but it's the key to this perfect crust. Even better, no butter! This usually yields about 1 1/2 apple pie's worth so I keep the extras in a ball in the freezer - perfect for pumpkin pie, chicken pot pie or for a crusty top to beef stew.

4 cups flour
1 tbsp sugar
