Yield: 8 servings.
½ cup packed dark brown sugar
¼ cup butter, melted
2 teaspoons fresh lemon juice
½ teaspoon ground cinnamon
¼ teaspoon ground cardamom
¼ teaspoon fresh nutmeg
2 Golden Delicious apples, peeled, cored, sliced ¼-inch thick
2 Anjou or Bartlett pears, cored, sliced ¼-inch thick (do not peel)
1 (9 x 13-inch) sheet frozen puff pastry, thawed
Powdered sugar, for garnish
Preheat oven to 425°. In a small bowl, combine brown sugar, melted butter, lemon juice, cinnamon, cardamom, and nutmeg. Spread onto a parchment-lined baking sheet. Top with sliced apples and pears. Roast for 15 minutes. Remove from oven and set aside.
Line a 9 x 13-inch baking sheet with parchment paper. Unfold puff pastry and place onto the baking sheet, pressing lightly to fit evenly in the corners of the pan. Using a paring knife, make a shallow cut around the border of the pastry, 1 inch from edges. Generously prick bottom of pastry with a fork. Bake for 10 minutes or until lightly golden.
Place apples and pears on top of pastry. Spoon any remaining sugar syrup over apples and pears. Bake 7 to 10 minutes more or until pastry is golden brown. Garnish with a dusting of powdered sugar just before serving.
