Crumb-Topped Apple Slab Pie
- Line a 15x10x1-inch baking pan with 18-inch-wide foil, extending the foil up over the edges of the pan; set aside. For dough: In a large bowl, stir together the 2-1/4 cups flour and the salt. Using a pastry blender, cut in shortening until mixture resembles coarse crumbs. Sprinkle 1 tablespoon of the cold water over part of the flour mixture; gently toss with a fork. Push moistened dough to side of bowl. Repeat, using 1 tablespoon cold water at a time, until all of the flour mixture is moistened. Using your fingers, gently knead the dough just until a ball forms.
- Preheat oven to 375F. On a lightly floured surface, roll dough into a 19x13-inch rectangle. Wrap it around the rolling pin; unroll it into the prepared baking pan. Ease dough into the pan and up the sides, being careful not to stretch it. Trim dough to 1/2 inch beyond edge of pan. Fold dough edge over and flute as desired.
- In an extra-large bowl, combine sugar, the 1/3 cup flour, and the cinnamon; add apples. Toss lightly until apples are coated. Spoon apple mixture into dough-lined pan; spread evenly. Sprinkle with Crumb Topping (pan will be full).
- Bake for 40 to 45 minutes or until apples are tender. If necessary to prevent overbrowning, cover top with foil for the last 5 to 10 minutes of baking. Cool slightly in pan on a wire rack.
- Serve warm or cool completely. Cut into rectangles. Makes 25 servings.

For Robyn's version, substitute 1/2 cup packed brown sugar for the 2/3 cup granulated sugar that is combined with the sliced apples. When the apple mixture is placed in the crust, drizzle with 1/2 cup homemade caramel sauce or purchased caramel ice cream topping. For the crumb topper, substitute 1 cup pretzel pieces for the oats.
- In a large bowl, stir together quick-cooking rolled oats, packed brown sugar, and all-purpose flour. Using a pastry blender, cut in butter until topping mixture resembles coarse crumbs. Stir in chopped pecans.
