Recipe: Deep Dish Apple Pie

I have never made an apple pie before! Not even in culinary school. I was more partial to cream pies (especially coconut). Since we're in apple season, I decided to give it a whirl. The recipe was pretty easy to follow, and it tasted really really good. My only complaint is that after baking  I couldn't get the slices to stay in shape. Can anyone tell why this happened? The only thing I could think of is that my apple slices should've been thinner...

See what happened when I sliced into it!

 Here's the recipe (courtesy of Food Network):

Ingredients

• 3 tablespoons butter
• 2 pounds Granny Smith apples, sliced 1/2-inch thick
• 2 pounds Macintosh Apples, sliced 1/2-inch thick
• 1/2 cup sugar
• 1/2 cup light brown sugar, packed
• 1 lemon, juiced
• 4 tablespoons all-purpose flour
• Pinch ground nutmeg
• 1 teaspoon ground cinnamon
• 1/2 teaspoon salt
• 1 cup pecan pieces (we did not use nuts)
• 1 recipe Pie Dough, recipe follows
• 1 egg, beaten

Directions

Preheat the oven to 350 degrees F.

In a large saute pan, melt the butter. Add the apples and saute for 2 minutes. Add the sugars, lemon juice and flour. Continue to saute for 2 minutes. Season the apples with nutmeg, cinnamon, and salt. Mix thoroughly and remove from the heat. Mix in the pecans. Cool the mixture.

Lightly dust a surface with flour. Cut the dough in half. Roll out each half to 12 inches in diameter and about 1/8-inch thick. Fold 1 circle of dough in fourths. Carefully lift the dough and place in a 10-inch deep-dish pie pan. Unfold the pie dough and spoon the apples into the pie shell. Place the second round of dough over the apples. Using a sharp knife cut away the excess dough. Using your fingers, crimp the edges of the pie firmly to seal the dough completely. With the same sharp knife, make 3 slits, about 4 inches long and 2 inches apart, across the pie dough. Brush with the beaten egg, place the pie in the oven, and bake for 1 hour and 15 minutes.
  
Pie Dough:

2 1/2 cups all-purpose flour
1 1/2 tablespoons sugar
3/4 teaspoon salt
11 tablespoons cold unsalted butter, cut into 1/4-inch pieces
3 tablespoons solid vegetable shortening
5 tablespoons ice water

Sift the flour, sugar, and salt into a large bowl. Using your fingers, work in the butter and shortening until the mixture resembles coarse crumbs. Add 4 tablespoons of ice water and work with your fingers until the water is incorporated and the dough comes together. Add more water as needed just until the dough comes together, being careful not to over mix. Form the dough into a disk, wrap tightly in plastic wrap, and refrigerate for at least 30 minutes before using.
