Peel, core, and slice the apples into wedges, place in a large bowl, and toss with the lemon juice.
Sprinkle the white sugar, brown sugar, cinnamon, nutmeg, salt, and flour over the apples and mix with your hands so the fruit is coated with the dry ingredients.
Roll out one disc of pie crust dough and place it in a pie pan.
Fill the crust with the apple mixture and tamp down.
Dot with three tablespoons of butter.
Roll out the second crust to fit over the apples.
Place on top of the pie.
Crimp the edges to seal and cut a few steam vents on top. Alternatively, cut the pastry into strips and create a lattice-style top.
Brush the top of the pie with an egg wash made with one egg and a tablespoon or two of water, and then sprinkle with a bit of sugar.
Bake for 10 minutes at 425 degrees.
After 10 minutes, loosely cover the top of the pie with foil.
Reduce the temperature to 350 degrees and continue baking for 40 to 50 minutes.
Remove the foil for the last 5-10 minutes of baking if you want it to brown more.
The pie is fully cooked when the fruit bubbles up through the vents or lattice.
Let cool for at least one hour before serving.
