Pie crust is simple, but requires technique. Get a dough cutter and keep everything cold while working (cold milk or water, frozen butter or lard core into small pieces, cold bowl, even chill the flour of you want). Butter and/or lard needs to stay in tiny lumps in the dough and not melt until it's in the oven cooking.
@Sally PB - above is true. Cold, cold, cold. You might like using a pastry cutter, to cut in the butter by hand - you can control it really well. But, many people use a food processor and metal blade to cut the butter/fat into the flour mix quickly. You then dump the crumbly mix into a bowl to add in the ice cold water. I sometimes cut it in by hand, sometimes use the food processor. But there is a learning curve to getting the moisture level just right as well. Always chill the dough before rolling it out. Often chill it again once in pan.
Although the recipes are typically just fat, flour, and water... I have one pie crust recipe that uses egg in the mix, and another that uses vodka (they give the science behind why the vodka is added, but I’d have to reread it).
Anyway, nothing better than eating your first successful pie crust, browned, flaky, yummy! Good luck for your next time!
