Cookie Sheet Apple Pie

• 6 cups all-purpose flour
• 1-1/2 teaspoons salt
• 1-1/2 teaspoons baking powder
• 1-1/2 cups shortening
• 6 large egg yolks
• 3/4 cup plus 4-1/2 teaspoons water
• 3 tablespoons lemon juice
• 8 cups sliced peeled tart apples
• 1-1/2 cups sugar
• 1 cup crushed cornflakes
• 1 teaspoon ground cinnamon
• 1/2 teaspoon ground nutmeg
• 1 large egg white, lightly beaten

1. 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.
2. 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.
3. Roll out remaining dough to fit top of pie; place over apples. Seal edges; cut slits in top. Brush with egg white. Bake at 400u0b0 for 15 minutes. Reduce heat to 350u0b0; bake 20-25 minutes longer or until golden brown.
