For the top crust of the pie, you can slice or poke it however you like. I like just making a few slices, but you could easily make a lattice crust. You could even use cookie cutters to cut out the dough and make a pretty arrangement.
Make sure to brush the crust with milk or egg wash and sprinkle the top with sugar to give it that golden color and a little sweet crunch.
If while baking the edges start to get too brown before you can wrap them in tin foil and then place back into the oven to finish baking.
