Bake the pie:

1. Cover with pastry: Unroll the puff pastry disc and cover the pie with it. Seal the pie by pressing the pastry disc firmly on the sides of the dish. I used a fork and pressed and crimped all around the pie dish. Trim off the excess pastry. You could use this excess to cut out leaves or flowers to decorate the pie with. It is not a necessary step.1 disc puff pastry
2. Egg wash: In a small bowl, mix the egg yolk and the milk. Brush the pastry with this mixture. Place the leaves or flowers on top of the pie and brush them with egg as well.1 egg yolk + 2 tablespoons milk
3. Bake: Make a small slit in the form of an X in the middle of the pie and some simple slits two or three times around the edges of the pastry. Bake for about 20 minutes until golden brown.
