Hi,
If I want to have a pie in the oven asap, I make a pie with shortening. Upon finishing the dough, I can immediately begin rolling it out.
If I plan ahead, I will use leaflard and/or butter. Both need chilling before they are rolled out.
I use a pastry cutter to cut in the fat. I almost never use a food processor, because I found it tended to heat the dough.
If recipe calls for 3-5 tablespoons of water, I go straight to the maximum. A moisture dough is easier to handle than a dry one.
I add water and stir with as few strokes as possible. Once I can form it into a ball, I stop fiddling with it.
If I am chilling the dough, I divide the dough (60:40) to form them into disks for bottom and top respectively.
When I roll pies out, I do it between very, very lightly floured wax or parchment paper.
The winter I decided to learn how to make pie, I was making pies several times a week. Like other techniques, it comes down to practice, practice, practice.
Regards,
