I wasn't worried about you being picky - it's just that pie crust is the one thing I don't make from scratch. My grandmother wouldn't teach me how to make it because she could never get my mother to do it "right". I just use the ones in the dairy case. LOL Gram's wasn't really a recipe anyway - more of "just add x until it looks right"!
Keeping that in mind, I have a recipe, but I don't know for certain if it's flaky since I use the ready-to-use. It should be, though, from the ingredients & instructions . . . PLUS it's from the Mennonite Community Cookbook & they're known for their great pies!
Pastry for a 9" double crust pie
2 1/4 c flour
2/3 c shortening
1/2 tsp salt
1/3 c cold water
Combine flour & salt in a mixing bowl. Cut shortening into flour with a pastry blender or 2 knives. DO NOT OVERMIX!! These are sufficiently blended when the particles are the size of peas.
Add water gradually, sprinkling 1 tablespoon at a time over the mixture. Toss lightly with a fork until all particles of flour have been dampened. Use only enought water to hold the pastry together when it is pressed between the fingers. It should NOT feel wet. (This is the step that confounded my mother!

)
Roll dough into a round ball, handling as little as possible. Roll out on a lightly floured board into a circle 1/8" thick and 1" larger than the diameter of the top of the pan.
I hope this helps!
