Sure! Julia's recipe is just like this but a bit more masochistic. She has you baste the cooking
apples with a blub baster the whole time. (The masochistic part is cleaning the stove afterward.) I've always used regular pastry dough for this but puff pastry sounds nice. Why not make a recipe more work if you can?
Seriously, the reason I make my own puff pastry is that I can't find a store-bought brand that uses real butter. (I know DuFour makes one but I haven't seen it in California.) It's not that hard to do once you get the hang of it.
