2-1/2 cups all-purpose flour1 tablespoon sugar3/4 teaspoon salt1/2 cup cold unsalted butter, cubed1/3 cup cold shortening5 to 7 tablespoons ice waterFILLING:1/2 cup dried currants or raisins2 tablespoons dark rum or water1 cup fresh or frozen cranberries, divided3/4 cup sugar, divided6 medium baking apples, such as Fuji or Braeburn (about 2 pounds), peeled and cut into 1/4-inch slices2 tablespoons quick-cooking tapioca1 tablespoon lemon juice2 teaspoons grated lemon zest1/2 teaspoon ground cinnamonEGG WASH:2 teaspoons sugarDash ground cinnamon1 large egg1 tablespoon 2% milk or heavy whipping cream

Preparation

In a small bowl, mix the flour, sugar and salt; cut in butter and shortening until crumbly. Gradually add ice water, tossing with a fork until dough holds together when pressed. Divide dough in half. Shape each half into a disk; wrap. Refrigerate for 30 minutes or overnight.

In a small bowl, combine currants and rum; let stand for 20 minutes.

Place 3/4 cup cranberries and 1/4 cup sugar in a food processor; pulse until cranberries are coarsely chopped. Transfer to a large bowl. Add the apples, tapioca, lemon juice, lemon zest, cinnamon, remaining 1/2 cup sugar and currant mixture; toss to combine. Let stand for 15 minutes. Preheat oven to 400°.

On a lightly floured surface, roll half the dough to a 1/8-in.-thick circle; transfer to a 9-in. deep-dish pie plate. Trim crust to 1/2 in. beyond rim of plate. Add filling.

Roll remaining dough to a 1/8-in.-thick circle; cut into 1/2-in.-wide strips. Arrange over filling in a lattice pattern. Trim and seal strips to edge of bottom crust; if desired flute edge. Place remaining cranberries in spaces between lattice strips.

For egg wash, in a small bowl, mix sugar and cinnamon; set aside. In another bowl, whisk egg and milk; brush over lattice top. Sprinkle with sugar mixture.

Bake on a lower oven rack, 25 minutes. Reduce oven temperature to 325°; until crust is golden brown and filling is bubbly, 40-45 minutes longer.

Cool on a wire rack for 30 minutes; serve warm.
