Preheat oven to 425 degrees F. Set apples in one bowl and sugar mixture in another; add flour to sugar mixture. Place mascarpone cheese in a third mixing bowl; stir in the grated orange rind and mix well.

On a lightly floured surface, roll dough into a circle approximately ⅛ inch thick. Place dough on a nonstick cookie sheet, or line a regular cookie sheet with parchment paper. Neatly layer half the apple slices on the surface of the dough, leaving a 1-½ to 2-inch border all around. Sprinkle all the cranberries over the apples. Sprinkle half the sugar-and-spice mixture over this, then dot with teaspoon-sized dollops of the mascarpone mixture. Top with remaining apple slices and sprinkle with remaining sugar-and-spice mixture.

Fold sides of dough up and over the edge of the filling. Brush dough with egg, and sprinkle dough and filling with 2 tablespoons sugar. Place an additional baking sheet underneath to catch any drips. Bake 10 minutes; lower oven temperature to 375 degrees F and bake 20 minutes longer. Remove from oven when golden brown; cool 20 minutes.
