I learned an excellent pie trick from a pastry instructor at work today. Bake your pie on the bottom shelf! Then your bottom crust will cook as fast as the top since it's closer to the heating element and it won't be soggy. WORD. I am employing this trick at this very moment, in fact. My house smells like blueberry heaven.
Incidentally, regarding blueberry pie: I use Elise's filling and Ruhlman's 3:2:1 pie dough for the crust. This time around I'm trying pastry flour because I thought it might make a more tender crust. Will report back.
