Preheat your oven to 350°F (175°C).

Prepare the Crust:

In a large bowl, mix together the flour, 1 tablespoon of sugar, and salt.

Cut in the shortening using a pastry blender or two forks until the mixture resembles coarse crumbs.

In a small bowl, beat the egg yolk and mix it with the milk. Stir this into the flour mixture just until the dough comes together.

Divide the dough in half. Roll out one half to fit the bottom of a 9x13 inch baking pan. Lay the dough in the pan.

Add Corn Flakes Layer:

Sprinkle the crushed corn flakes evenly over the crust in the pan. This layer helps absorb the juices from the apples and keeps the crust from getting soggy.

Prepare Apple Filling:

In a separate bowl, combine the sliced apples, 1/2 cup sugar, and cinnamon. Toss to coat the apples evenly.

Spread the apple mixture over the corn flakes layer.

Top Crust:

Roll out the second half of the dough and place it over the apple layer. You may choose to make a lattice top if you prefer.

Egg White Topping:

Beat the reserved egg white until stiff peaks form. Gently spread this over the top crust. This will give a nice sheen and a slight crispness to the crust.

Bake:

Bake in the preheated oven for about 45-50 minutes or until the crust is golden brown and the apples are tender.

Cool and Serve:

Let the apple slices cool in the pan on a wire rack. Once cooled, stir together ingredients for glaze and drizzle it over the top of the baked apple slices. Cut into squares and serve.

These apple slices can be enjoyed as they are, or with a dollop of whipped cream or a scoop of vanilla ice cream.

Enjoy your homemade apple slices!
