For the Apple pie crust I've always made I just use an old recipe from an old cook book I've had around for long time. I use vegetable shortening, yes I now FAIL but anyway. Basically I just mix the flour, water, eggs, sugar, salt, shortening, ect... together till the consistency is right. Form 2 balls for both 1/2s of the pie and roll them out. Simple as can be. I know the probably way involves a lot more steps and making sure it's always cold as you say but the crusts I make this way have always turned out very well.
