Preheat the oven to 350°F. Toss the apples with the brown sugar, sugar, flour, lemon juice, cinnamon, nutmeg, cloves, and salt.
7 cups Granny Smith apples*, ½ cup brown sugar, ½ cup granulated sugar, ¼ cup all-purpose flour, 1 tablespoon lemon juice, 2 teaspoons ground cinnamon, ¼ teaspoon ground nutmeg, ⅛ teaspoon ground cloves, ¼ teaspoon kosher salt
Line a 9-inch pie dish with one crust, cutting away any excess dough from the edges.
2 9-inch refrigerated pie crusts**
Transfer the apples to the pie crust. Pour half of the caramel sauce over the apples. Then, sprinkle with flaky sea salt.
1 cup caramel sauce***, ½ teaspoon flaky sea salt
For a lattice crust, place the 2nd crust on a floured surface. Use a pizza cutter or knife to cut the dough into long strips about 1-inch wide. Evenly drape 5-6 strips over the pie in a vertical direction, leaving about one inch in between each strip. Peel back every other strip, stopping in the middle of the pie. Place a strip in the middle of the pie in a horizontal direction. Fold back the strips. Then, peel back the other vertical strips. Place a second strip horizontally about 1 inch apart from the middle strip. Then, fold back those strips. Continue this sequence for the remainder of the strips. Trim the excess dough spilling over the pan. Pinch the ends of the strips into the edges of the bottom crust. Crimp the edges.
Whisk together the egg and water. Then, brush the egg wash over the pie crust. Sprinkle the turbinado sugar over the crust.
1 large egg, 1 tablespoon turbinado sugar
Place the pie on a baking sheet, and bake for 30 minutes.
Check the pie and cover the outer crust with tin foil if becoming too browned. Bake for another 20-30 minutes until the filling is bubbly.
Let the pie cool before serving slices topped with the remaining ½ cup of caramel sauce.
