This only happens some of the time but I cannot figure out why. The crust will stick to the foil which is lining the pan sometimes. In the past I have put parchment paper between the crust and the foil and that worked but then I found I didn’t need it until today when the crust stuck to the foil again. It peels off if you gently pull on it but it would be nice to know why it does this some of the time. Maybe it depends on the moisture of the dough or the gluten content, I don’t know. Any thoughts would be most appreciated.
