It doesn’t get easier than this!
I prefer to buy ready-to-use puff pastry sheets that are sold individually. So you get one sheet, rolled and not frozen, and you just take it out of the package at home and that’s it.
If you can’t find this at your store, just use frozen puff pastry instead. From my experience the sizes of store-bought puff pastry dough are all pretty similar, whether they come rolled and ready or frozen in boxes and you roll them yourself.
I grate my apples with a classic box grater. As you grate the apples, they release some juice, which is why adding the breadcrumbs is important, as they soak up some of that juice.
Make use of the apple peels and cores! Instead of discarding them, make this apple peel tea. It’ll go great with these pies.
