2 1/2 cups all-purpose flour
1/2 teaspoon salt
1 large egg, divided use

Milk
1 cup butter
6 to 8 tart green apples
1 1/3 cup granulated sugar
1/8 teaspoon salt
1/2 teaspoon ground cinnamon
4 tablespoons all-purpose flour

Granulated sugar for sprinkling

1. Combine 2 1/2 cups flour, butter and salt with a pastry blender.
2. Separate egg; set aside egg white at room temperature. Put egg yolk into a glass measuring cup and fill with milk to measure 2/3 cup. Pour into the flour mixture and mix well.
3. Divide dough in half and roll out on a lightly floured surface to fit a cookie or baking sheet. Save other half of dough for top crust.
4. Peel, core and slice apples. Arrange slices in side by side rows on unbaked bottom crust to make 1/2-inch layer.
5. Combine sugar, salt, cinnamon and 4 tablespoons flour, mixing well. Sprinkle mixture over apples.
6. Roll out top crust and place over apple slices, pinch and seal edges.
7. Beat the egg white until stiff and spread over the top of crust. Sprinkle 1 to 2 tablespoons sugar over the top of egg white.
8. Bake at 450* (230*F) for 10 minutes. Reduce to 400*F (205*C) and bake about 20 to 25 minutes or until golden brown. Cool and cut into 2 1/2-inch bars.

Makes about 36 bars.
