I will be honest and admit I used pie crust from the grocery store (anyone who has a problem with that can come and do my laundry while I make crust from scratch because I just dont have time to dither about with something I can easily purchase and tastes just as good - in fact, people are always asking me for my pastry recipe lol!) I let the crust warm up enough to take it out of the pan and roll it out. This is important because when I assembled the crust it amounts to a few layers of dough so they should be thin to not make an inch of top crust. I used 4 pie crusts to make this pie but it is worth it!
I cut out around 100 leaves and put them in a container between layers of waxed paper and put them in the freezer. This is the kind of thing that can be prepped in advance so hours aren't spent on one pie in one day. I filled a 3rd pie crust with my apple pie filling (apples, cinnamon, spices, brown sugar) and rolled out the 4th pie crust to make it thinner before putting it on top of the pie.
I used water to 'glue' the leaves onto the top crust and worked my way around until it was covered.
Have a fabulous day!
