Line a baking sheet with parchment paper and preheat oven to 350 degrees F. In a large mixing bowl, pour 1/3 cup lemon juice and 3 tablespoons granulated sugar over 8 large Granny Smith apples (peeled and diced). Using a spatula, stir to make sure apples are fully coated. Set aside.
In a small bowl, mix together 1/2 teaspoon ground cinnamon, 1/2 teaspoon ground nutmeg, 1/4 teaspoon ground allspice, 1/4 teaspoon table salt, and 2/3 cup packed light brown sugar until combined.
Pour brown sugar/spice mixture over the diced apples and stir until the apples are fully coated. Stir in 2 tablespoons minute tapioca (optional).
Roll out one pie dough sheet and place over your pie dish, pressing into make sure it is flesh against the dish. Take a fork and make a few punctures in the bottom of the dough. Sprinkle 2 tablespoons graham cracker crumbs (optional) over the crust.
Pour apple mixture into the prepared pie dish. Stir 1 1/2 tablespoons sea salt into 2/3 cup caramel sauce and pour over the apples.
Create a lattice design with the second pie dough sheet and place over the top of the pie. Use a fork to pinch edges.
Use a fork to lightly beat 1 large egg and 1 teaspoon milk until blended. Brush the egg wash over the crust of the pie. This will help give it a golden brown color.
Place the pie on the baking sheet on the middle oven rack and bake for 35-45 minutes or until the crust is golden brown and the juices are bubbly. Allow the pie to cool before serving.
Notes
Place foil around the edges of the crust if your oven runs warm to avoid the crust burning.
To get a little bit more of a salt flavor, soak your apples in a salt bath before mixing in your spices/sugar. Just make sure to dry with a paper towel
Pie will keep for 3 days at room temperature or 5 days in the refrigerator.
