1 graham cracker crust
1 lg. egg yolk, beaten
5 1/2 c. sliced, cored, peeled cooking apples
1 tbsp. lemon juice (omit if apples are very tart)
1/2 c. sugar
1/4 c. brown sugar, firmly packed
3 tbsp. all purpose flour

1/2 tsp. cinnamon
1/2 tsp. nutmeg
3/4 c. all purpose flour
1/4 c. sugar
1/4 c. light brown sugar, firmly packed
1/3 c. butter at room temperature

Preheat oven to 375 degrees. Brush bottom and sides of crust with yolk. Bake on cookie sheet until light brown, about 5 minutes. Remove from oven. Combine apples, lemon juice, 1/2 cup sugar, cinnamon and nutmeg. Mix well and spoon into crust. Mix remaining flour, sugar, brown sugar, and butter with fork or pastry blender until crumbly.
