Basic Flakey Pie Crust

Hadn't made a pie in a while; thought I'd give it a go. Figured it be a good opportunity to finally break out Rose Levy Beranbaum's The Pie and Pastry Bible. Today I just made the Basic Flakey Pie Crust. I'll get to the filling and baking later this week. Only so much time in the day. Right now I'm leaning towards the Open-Faced Double Strawberry Pie. Sounds good, no? And strawberry's are in season. Stay tuned for that. As seen below, the crust contains butter, pastry flour (I used cake flour, should have added some all-purpose), salt, baking powder, ice water, and a bit of apple cider vinegar.
