Ingredients:
2 cups all−purpose flour
1/2 cup white sugar
1/4 teaspoon salt
3/4 cup chilled butter, diced
2 egg yolks, beaten
1 1/4 pounds Golden Delicious apples − peeled, cored and cut
into 1/4 inch slices
1/4 cup light brown sugar, packed
1 tablespoon all−purpose flour
1/2 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg

Directions:
Preheat oven to 400F. Sift four, 1/2 cup sugar and salt into a large bowl.
Cut in butter until mixture resembles coarse crumbs. Fold in egg yolks (mixture will be crumbly). Remove 1/4 of mixture, and set aside. Press remainder onto bottom and sides an 8 inch tart shell or pie pan. In a large bowl, combine apples, brown sugar, 1 tablespoon flour, cinnamon and nutmeg.
Place apples into crust, and sprinkle reserved crumb mixture evenly over top. Place pie on a baking sheet, and bake in preheated oven for 15 minutes.
Reduce heat to 350F and continue baking 20 minutes, or until top is golden brown and filling is bubbling.
