As the summer days draw to an end, my heart is filled with an intense longing to share with you this dreamy apple blueberry pie. Its sweet and tart fruit filling, made by combining freshly picked apples with fresh blueberries, is like the perfect blend of the warm Summer sun and the crisp Fall breeze. It's a perfect farewell to summer and a warm welcome to Autumn.

Instructions
Shortbread Pie Crust
Preheat oven to 400 degrees F or 204 C
Prepare pie mold by greasing generously with butter or spraying with baking spray
In the bowl of a stand mixer with a paddle attachment or a large bowl with a hand mixer, cream butter, salt, vanilla, and sugar for 2 to 3 minutes or until the butter has taken on a deeper yellow color; that’s a good indicator that your ingredients are creamed
Sift in flour, and stir well, eventually using your hands to create a dough
Press the dough into the prepared pie pan and fork with holes to prevent the butter from bubbling. Bake in the preheated oven for 10 minutes minutes. Your cookie will still be soft and fluffy. It will harden more once removed from the oven. While it's in the oven, make your pie filling. Keep oven heated
Apple Berry Filling
Simmer berries, apples sugar, and lemon juice in a large saucepan over medium heat until warm and juicy, about 5-10 minutes, gently stirring occasionally.
Add in your cornstarch, gently mix in with the apples and berries to prevent mashing them, and check the consistency. It should be thick and gel like. If it's too soupy, gently sprinkle cornstarch and mix until thickened.
Remove from heat and stir in the butter. Allow it to cool for 10 minutes.
Pour on top of the shortbread cookie crust.
This recipe is versatile, you can make a simple crumble topping, like from our pumpkin shortbread bars, or use a homemade or storebought pie crust.
Pie Crust Top
And pie crust top. If not using a lattice top, poke holes in the top to allow steam to escape.
Brush a thin layer of beaten egg white over the top of the pie and sprinkle lightly with coarse sugar, if desired.
Bake
Bake at 400 degrees F for 40-45 minutes. After about 30 minutes, check it and place a piece of foil over it if the top crust is getting brown too quickly.
Move pie pan to a wire cooling rack and allow it to cool for several hours.
Notes
Serving a storage:
The pie should cool completely before serving for at least 2 hours. If sliced when warm, the filling may spill out and not be set.
The pie may be stored at room temperature overnight.
Store leftovers in the refrigerator for up to 3 days.
