The KEY to pastry dough, folks, is when you "cut" in the butter or lard or shortening...., it MUST be cold. When you add it to the flower and mix it up, when done you want it to look like small balls a tiny bit bigger than peas, but pea size works, then roll it out once, and put into your pie pan or cover your pie. When it's too warm, or you over mix it, the lil pockets of fat among the flour are too small and it's them lil pockets of fat that cause it to be flaky.
The other solution is to go to the biscuit section of your local super market, and you will find chilled, ready to apply, pie crusts. Two to a box, buy one box, then go to the frozen dessert section and buy a pair of frozen pie crusts in pans. Pre-bake the frozen pie crusts for 15 minutes or so, then fill, and cover with one of the chilled pie crusts above. This makes two pies, and less mess.
