Step 1

Roll out your chilled pie dough into a disk about 1/4 inch thick and an inch or so larger than your pie dish. Transfer the dough into the pie dish leaving half an inch of overhang. Trim the edge as needed then fold under and crimp the edge. Transfer to the freezer to chill while you make the filling.

Step 2

Add the flour, salt, sugar, and cinnamon to a bowl then mix until combined. Pour in the melted and cooled butter then mix once more. If the butter is too warm the mixture will form a glob instead of crumbles.Just pop in the fridge to chill a few minutes and break up with your hands if that happens.

Step 3

Peel, core and slice your apples, then toss with the lemon juice. Cut your apples into similar sized pieces so they cook at the same rate.

Step 4

Add the sugar, cinnamon, and nutmeg then toss to combine evenly.

Step 5

In a large skillet, melt the butter over medium-high heat. Add the apples, and cook, stirring, until the sugar dissolves and the mixture begins to simmer, about 2 minutes. Cover, reduce heat to medium-low, and cook until the apples soften and release most of their juices, about 7 minutes. While the apples are cooking down you can mix in the corn starch.

Step 6

Pour the apples into a strainer set over a large bowl. Set the apples aside and pour juice back into the pan. Cook at medium-high heat stirring frequently until the liquid bubbles vigorously and thickens. The liquid will be thickened to the consistency of caramel when It's ready.

Step 7

In a medium bowl, toss the apples with the reduced juice. Set aside to cool completely.

Step 8

Heat oven to 400F. Mix the egg and cream, or milk in a small bowl then Brush the edge of the pie with it. This is optional but gives your crust a golden finish.

Step 9

Add your filling to the dish and smooth out surface with a spatula.

Step 10

Sprinkle the crumble on top of the pie covering the surface completely. Transfer the pie dish to a baking sheet then loosely wrap the edge with foil. This will prevent the pie from burning while you wait for the center to bake through.

Step 11

Bake at 400F for 15 minutes then reduce the temperature to 350F and bak an additional 50 minutes or until golden brown in the center. You can remove the tenting in the last 20 minutes If the edge needs some color.
