Combine the fruit in a large bowl with:
Spread the fruit mixture evenly in the baking dish. Dot with:
Remove the dough from the refrigerator and let stand for a few minutes, until pliable, then arrange the dough over the top of the apples. Tuck the edges of the dough into the dish. Bake until the top has browned lightly, about 30 minutes. Remove the dish from the oven and reduce the oven temperature to 350°F.
With a knife, score the crust into 2-inch squares. Baste the crust squares by tilting the pan and spooning the juices over them; or submerge the squares in the juices with the back of a spoon. Return the dish to the oven and bake until the fruit is tender when pierced with a skewer, the filling has thickened slightly, and the crust is golden brown, about 30 minutes more. Let cool for 15 minutes before serving.
