APPLE-RAISIN CINNAMON BUN PIE

Steps:

• Line a 9-inch pie plate with 1 piece of dough, and refrigerate until ready to assemble the pie.
• Make the cinnamon-roll crust: Lay the remaining piece of dough on a lightly floured surface, and spread 2 tablespoons of the butter evenly on top. Combine 1/4 cup of the granulated sugar and 1 teaspoon of the cinnamon in a small bowl, and sprinkle evenly over the butter; gently press with your fingers to help the mixture adhere. Roll the dough up into a tight log. Trim and discard about 1 1/2 inches from each end, and cut the remaining log crosswise into 1/2-inch-thick pieces. Arrange the pieces, cut-side down, in a snug circle on floured parchment paper. Lightly dust the pieces with flour, then gently roll out into a 10-inch round. Slide the parchment onto a baking sheet, and refrigerate until ready to assemble the pie.
• Put the dark and golden raisins in a medium bowl with hot water to cover. Let them soak until tender, about 5 minutes, then strain.
• Make the filling: Peel and core the apples, cut them into 1/2-inch-thick slices and toss with the remaining 1/2 cup sugar and the lemon juice in a large bowl. Melt the remaining 4 tablespoons butter in a large skillet over medium-high heat. Add the apples, and cook, stirring occasionally, until the firmer apples soften but hold their shape, 15 to 18 minutes. (The softer apples, like McIntosh, will get very soft and saucy.) Add the flour, the remaining 1/2 teaspoon cinnamon, and the nutmeg and salt, and stir until the juices thicken, about 2 minutes. Remove the skillet from the heat, stir in the raisins and let the filling cool completely. (The filling can be refrigerated, covered, for up to 2 days.)
• Fill the dough-lined pie plate with the filling in an even layer. Invert the cinnamon-roll crust on top, and peel off the parchment. (It's OK if the individual rounds separate a bit in the process.) Pinch the crusts together. Fold the overhanging dough under itself, and crimp as desired. Brush with the egg, and refrigerate for 30 minutes.
• Bake the pie: Place a baking sheet in the oven, and preheat to 400 degrees F. Set the pie on the hot baking sheet, and bake until the crust is golden brown and the filling is bubbling, about 50 minutes. (Tent loosely with foil if the top browns too quickly.) Transfer to a rack to cool slightly.
• If using a glaze, whisk together the confectioners' sugar and milk in a bowl until smooth. (Add more milk if the glaze is too thick.) Drizzle over the pie.
