Favorite Pie Crust

I got this pie crust recipe from a roommate who would make the best apple pie. It's the best pie crust recipe I've found that I like. It makes enough for about 2.3 crusts, or if you roll it thinner, 3 crusts. I don't usually roll it thin enough for 3 crusts, but in theory, you could.

3 cups flour
1 tsp salt
1 1/3 cup shortening

Cut/mix all these ingredients together.

1 egg

1 Tbsp vinegar

Cold water

In a 1 cup measuring cup, add egg and whisk it. Add vinegar and fill the rest of the cup up with cold water. Add to dry ingredients mixture. Roll out. It will be sticky. Roll it out with more flour. Divide in halves or thirds for use!
