Choose your apples. You need 5 pounds of apples for this recipe, which is about 11 large apples. I like to use a mix of apples for the best flavor. For this pie I used Granny Smith, Honeycrisp, and Golden Delicious.
Make the filling: Use a microplane grater to zest ¼ teaspoon lemon peel into a 12-inch high sided skillet. The heat should be off.
Add the juice from half the lemon to the skillet, about 2 tablespoons. Don't use much more than this, you're not making a lemon apple pie. We just want to wake up the apples a bit and keep them from browning.
Use a potato peeler or this handy apple peeler to peel the apples. Slice the apples into ⅛ inch pieces. I like to peel and slice one apple at a time so that they don't get brown: I peel one apple, then stop and slice it, add it to the pan with the lemon juice, and then move on to peeling the next apple. Stir the apples in the pan occasionally to coat everything with lemon juice.
Once you have all the apples peeled and sliced in the pan, set it over medium heat on the stove.
Add ½ cup packed brown sugar, ½ cup granulated sugar, ⅓ cup flour, ½ teaspoon kosher salt, 1 and ½ teaspoons cinnamon, ¾ teaspoon nutmeg, and ½ teaspoon cardamom (optional). Stir it together gently so you don't break all the apples.
Once the mixture is all moistened and you don't see patches of flour or cinnamon, set a timer for 20 minutes. Cover the mixture completely with a lid, but don't walk away. Stick around and stir the mixture every 3 minutes or so, replacing the lid each time. Cook for 20 minutes, until the apples are fork tender but still hold their shape.
Remove the pan from heat and stir in 1 teaspoon vanilla.
Transfer the apple pie filling to a half sheet pan, or any pan with a lip. Spread the apples all the way to the edges. Cool the apple pie filling completely by placing it in the fridge or the freezer.
Roll out your pie dough and place in a 9-inch pie dish. Fold the edges underneath and crimp them with your fingers and thumbs.
Place the pie crust in the fridge or freezer for about 30 minutes, for a really flaky crust.
While the crust and filling are chilling, place a baking sheet or pizza stone in the center rack of your oven and preheat to 425 degrees F.
Make the sugar crumble: In a medium bowl, add the dry ingredients for the crumble: 1 and ½ cups flour, ⅓ cup white sugar, ¾ cup packed brown sugar, and ½ teaspoon kosher salt. Whisk together.
In a small bowl, melt ¾ cup butter. Pour the butter over the dry ingredients and stir together gently. Let it chill in the fridge until you are ready to assemble.
When the apple pie filling in the freezer is completely cooled, and the pie shell is mostly frozen, take them out of the freezer. Use a rubber spatula to scrape all the chilled apple pie filling into the pie shell.
Use your hands or a fork to break the crumble into smaller bite size pieces. Top the pie with about a cup or two of the sugar crumble, not all of it! Place the remaining crumble back in the fridge to chill.
Bake the pie: Place the chilled pie onto the baking sheet in the oven and let bake for 15 minutes at 425 F.
After baking at 425 for 15 minutes, reduce the heat to 350 degrees F. Don't take the pie out of the oven. Just change the temperature. Bake at 350 for an additional 10 minutes.
At this point, remove the pie from the oven and quickly shut the oven door. Sprinkle the remaining chilled crumble all over the top of the pie. Place the foil on top of the pie crust. Loosely crimp it around the crust on the edge.
Don't forget that your oven temperature should be at 350. Place the pie back on the hot baking sheet in the oven and bake at 350 for about 25-35 more minutes.
You will know the pie is done when the edges of the crust are brown and the crumble is turning a light golden brown in the center. If you want your crust and crumble to brown a little more, remove the foil shield and bake another 5-10 minutes.
Let the pie cool on a wire rack for about 4 hours. Once the pie is completely cool, slice and serve!
