So many people have expressed either problems or tips for pie crusts, I think it would be a good idea to start a sub-thread.
So what problems do you have? Does it not taste nice? Does it crack?
I just use butter (which I keep in the fridge, but I think I've microwaved to soften before) flour and maybe a pinch of salt. Mush that together with your fingers till you get breadcrumbs, and that's pretty much it. you can put it in the fridge for 30 minutes, but I'm pretty sure in a rush, I've used it as-is.
