My mother, Helen, has been making this dessert for years and it is "world famous"! It's such a hit with family and friends and couldn't be easier! This can also, of course, be made with your own homemade pie crust and fresh apples, as well. It's also wonderful with other fruit fillings such as peach, raisin, cherry, etc. I just happen to love the quick and easy method!
Lay one unbaked pie crust onto a round pizza pan. Pour apple pie filling onto dough. You can add a little cinnamon sugar and nutmeg if the pie filling doesn't have enough for you.
Put other pie dough crust on top and crimp edges all the way around to seal in pie filling. Prick top crust with a fork.
Beat one egg white until stiff and spread onto top pie crust. Sprinkle egg white with some more cinnamon sugar. Bake at 350 - 375 degrees for 35 - 40 minutes, until bottom crust is baked and top crust is golden brown.
Add 1 tsp. of vanilla and a little hot water to 1 cup of powdered sugar until it is thin enough to drizzle on top of the apple crisp. Enjoy!
