Everyone seems to know that one of the best ways to celebrate Pi day is with Pie, right? Well this particular pie I'll be showing you how to make in this instructable is an Apple Blueberry Layer Pie, with the Pi symbol engraved on the top of the crust. The Blueberries are layered on-top of the apples so as to show through the symbol Pi because of its great contrast to the Pie crust.

Have fun baking!

Step 1: Ingredients

Ingredients: (makes one largish regular pie)

2 frozen pie crusts (or homemade)

2 cups of frozen blueberries

3 Granny Smith Apples

3 McIntosh Apples

2 teaspoons cinnamon

⅛ teaspoon nutmeg

½ cup sugar

¼ cup brown sugar

¼ teaspoon salt

¼ cup flour

1 tablespoon lemon juice

Sugar for garnish

1 egg white

NOTE:

It would be best to have a deep-dish pie pan for this recipe.

Step 2: Preparation

Place a room-temperature unbaked pie crust onto a pie pan, as shown. Leave the second pie crust on the counter to reach room temperature while you prepare the pie.

NOTE:

Having the pie crust defrosted completely to room temperature is important. If it is not at room temperature, it is going to be alot harder to place in the pie pan, because it will crack all over the place.

Usually with recipes, you'll see instructions at the very beginning to preheat your oven. But with a long recipe, like this, where it is about half an hour or so to prep, your oven will just be wasting energy. Because of this, you'll only need to preheat your oven in this recipe 10 - 15 minutes before you're ready to bake. It preheats at 425 degrees. You'll see "preheat oven to 425 degrees" in a much later step.

Step 3: Dry Ingredients

Combine flour, sugar, brown sugar, salt, nutmeg, and cinnamon in a small bowl.

Step 4:

Peel, core, and slice the apples, or use a very handy machine to do it for you. Toss the 'peeledcoredsliced' apples and lemon juice in a large bowl. Cut large pieces with a knife until all pieces are evenly sized.

Throw the flour-spice-sugar mixture over the apples, and toss to coat the apples completely.

Step 5: Add the Blueberries

Throw the apple mixture into the pie crust-filled pan.

Prepare the two cups of frozen blueberries by placing them in a colander and rinse thoroughly. Pat dry with paper towels. Even if you have fresh blueberries, you could also do this to wash them.

Evenly layer these blueberries over the top of the apples.

Now you may preheat the oven to 425 degrees. (Fahrenheit)

Step 6: The Top Pie Crust

Place the other room temperature pie crust over the top neatly, and, using a fork, press across the circumference of the pie pan, pressing the top pie crust into the bottom crust.

Using a stencil, or your own brain, carefully cut the Pi symbol (rather largely) out of the top pi crust. You can use the cut-out crust as extra decoration on the top of the pie crust if you want to.
