Heat oven to 425º F.
Put a large baking sheet on the middle oven rack.
Prepare pie crust.
Add the lemon juice to the apples as you are slicing them.
Whisk together sugar, flour, nutmeg, cinnamon and salt.
Gently add the dry mixture to the sliced apples and lemon juice.
Roll out one disk of pastry dough on a lightly floured surface with a lightly floured rolling pin into a 13″ round.
Fit into a 9″ pie plate.
Trim edge, leaving ½″ over-hang.
Pour apple mixture into pastry-lined pie plate.
Dot with the 2 Tablespoons of butter.
Roll out the second disk of pastry dough to about an 11″ round.
Cover with the top crust.
Seal the top crust to the bottom crust by pinching the two together.
Lightly brush top of the pie with egg and sprinkle with sugar.
With a sharp knife, make steam vents in the crust.
Cover the edge of the crust with aluminum foil and remove this 15 minutes before baking is finished.
Bake the pie on the baking sheet for 20 minutes.
Reduce heat to 375º F and bake until the crust is golden and the filling is bubbling through the vents. About 40 minutes.
Cool the pie on a cooling rack until warm or room temperature.
Serve with ice cream or whipped cream or caramel sauce and Enjoy!
