Instructions:

Step 1: Prepare the Dough
Combine the flour, salt, shortening, and the mixture of egg yolk and milk (to make 1 cup total) in a large bowl. Stir together until a smooth dough forms.

Step 2: Shape the Bottom Crust
Roll out half the dough to fit a 15×10-inch cookie sheet. Place it evenly in the pan.

Step 3: Add the Filling
Sprinkle 2 to 3 handfuls of Corn Flakes over the dough. Layer the sliced apples evenly on top.

Step 4: Season and Butter
Mix the sugar and cinnamon together, then sprinkle this over the apples. Dot the filling with cubed butter.

Step 5: Cover with Top Crust
Roll out the remaining dough and place it over the apples. Seal the edges by crimping firmly.

Step 6: Apply Egg Wash and Vent
Beat the egg with sugar and brush it over the top crust. Cut a few slits to allow steam to escape while baking.

Step 7: Bake the Pie
Bake at 425°F (220°C) for 25 to 30 minutes until the crust turns golden.

Step 8: Add Frosting and Serve
While the pie is still warm, whisk together powdered sugar, vanilla, and enough milk to form a thin glaze. Drizzle this frosting over the pie. Slice and enjoy warm.
