Cookie Sheet Apple Pie

Directions

• In a large bowl, combine the flour, salt and baking powder. Cut in shortening until mixture resembles coarse crumbs. Whisk the egg yolks, water and lemon juice; gradually add to flour mixture, tossing with a fork until dough forms a ball. Cover and refrigerate for 30 minutes.
• Divide dough in half so that one portion is slightly larger than the other. On a lightly floured surface, roll out larger portion to fit the bottom and sides of a greased 15x10x1-in. baking pan. Arrange apples over crust. Combine the sugar, cornflakes, cinnamon and nutmeg; sprinkle over apples.
• Roll out remaining dough to fit top of pie; place over apples. Seal edges; cut slits in top. Brush with egg white. Bake at 400° for 15 minutes. Reduce heat to 350°; bake 20-25 minutes longer or until golden brown.
