Place apples in a bowl, add one tablespoon lemon juice (to prevent browning) and toss apples.
1 Tablespoon Lemon Juice
Add granulated sugar and toss until apples are coated.
½ Cup Granulated Sugar
Cover bowl with a kitchen towel and set aside for one hour.
Crumble
Combine brown sugar, flour, oatmeal, butter, cinnamon and nutmeg in a bowl. Using your hands, or a stand mixer fitted with the paddle attachment, combine ingredients until it resembles coarse pieces.
¾ Cup Brown Sugar, ¾ Cup Oatmeal, ¾ Cup All-Purpose flour, ½ Cup Unsalted butter, 1 teaspoon Ground Cinnamon, ½ teaspoon Ground Nutmeg
Pie
Pour macerated apples into a colander placed over a bowl. Discard the juices.
Sprinkle cornstarch, salt, cinnamon and nutmeg over apples. Toss to coat apples evenly.
2 Tablespoons Corn Starch, ½ teaspoon Salt, 1 teaspoon Ground Cinnamon, ½ teaspoon Ground Nutmeg
Using a pastry brush apply egg wash to the pie shell (bottom, top and sides of crust)
1 Large Egg, lightly beaten
Place ½ of the apples into pie shell.
1 9" pan Sweet Pie Dough
Drizzle ½ of the caramel over apples.
Place remaining apples in pie shell and drizzle remaining caramel over the apples.
Spread crumble topping over pie filling. Press lightly with your hands to adhere crumble to the apple filling.
Place pie in refrigerator and heat oven to 350℉ (180℃). (note - placing pie in refrigerator helps alleviate issues with burnt and shrinking crusts)
Once oven heats up 350℉ bake for 35 - 40 minutes. Check crust after 25 - 30 minutes of baking. If crust is becoming too brown, place a pie shield over crust (or wrap loosely in foil).
Remove from oven and place on a wire rack. Cool completely before serving.
