Preheat oven to 450°F and spray a deep 9-inch pie dish with baking spray.
In medium bowl, mix together the apples, sugar, flour, cinnamon, salt, and bourbon.
Unroll one of the pie crusts and place into the pie pan.
Pour the apple mixture into the pie shell.
Place the butter over the apple mixture.
Place the last pie crust on top of the apple mixture.
Pinch the edges together using your fingers or a fork.
Using a small bowl, whisk together the egg and water.
Using a sauce brush, brush the top of the pie crust with the egg mixture.
Sprinkle the sparkling sugar on top.
Cut 4 slits into the top of the crust to make air vents.
Place pie onto a cookie sheet.
Bake in the oven for 15 minutes at 450°F and then bring the oven temp down to 350°F. Continue baking 30-45 minutes or until the top turns golden-brown.
Remove from oven and allow to rest for 15 minutes before serving with desired toppings.
