A heap of apples is what you need when making an apple pie
. Always prepare extra apples than you think you will need. Make a mountain in the pie shell when you add the apples. Stretch the top pie crust over the mountain of apples as best you can. You will find while the pie bakes the mountain of apples will deflate. You will be left with a pie that has a sufficient amount of apples. Without the mountain you may end up with a caved in pie and few apples per slice.
