Wonder if anyone can tell me what might have happened and how to prevent it from happening again:
A few days ago, I mixed a batch of pie dough (standard, all-butter, food processor), chilled it a few hours, then rolled it out to line my glass pie pan. I wrapped it well and froze it. Last night I moved the pan to the fridge to thaw, and then today set it out for an hour or so to come to room temp before blind-baking.
I baked it my usual way: prick with fork, line with foil, weigh down with dried beans, remove foil and beans for the last 10 minutes or so. Nonetheless, when the crust was ready to come out, the whole thing had shrunk: the pie crust is laying in the pie pan like a mismatched nesting bowl: the edges are holding it up (they didn't shrink), so it sort of hovers over the bottom of the pan.
I filled with pumpkin pie filling and and baking that off now anyway (whatever happens, ie., if it collapses, will still be edible).
But does anyone know what happened? Thanks in advance.
