Pioneer Woman's Pie Crust

I am intrigued by this pie crust - mainly because you can make it ahead of time and freeze it so that it's ready to go when you want to make a pie.  I've only used it once - for chicken pot pie (and it was delicious), but I plan on trying it with a pie soon.  

Ingredients:

3 Cups of flour

1 teaspoon of salt

1 1/2 Cups of margarine

1 egg

5 Tablespoons of cold water

1 Tablespoon of White Vinegar

Combine the flour and salt in a large bowl.  Add in the margarine.  Use a fork to work the margarine into the flour until the mixture resembles tiny pebbles.  This step should take 3-4 minutes.  Lightly beat the egg with a fork & then add it to the mixture.  Next add in the cold water and the vinegar.  Stir the mixture together until it's just combined, then remove half of the dough from the bowl.  If you want to use it immediately, roll it out and place it in your pie pan. Repeat this step for the top layer of your pie.  If you want it for a later date, place it in a large plastic bag & slightly flatten it with a rolling pin.  This makes it easier to roll it out after it's frozen.  Place it in the freezer and repeat with the other half of the dough.
