" Preheat oven to 375 degrees F. Grease a 9- by 13-inch baking dish with butter; set aside. In a large skillet over medium-high heat, melt 3 tablespoons butter. Add apples and cook, stirring occasionally, until just caramelized, about 10 minutes. Meanwhile, in a large bowl, mix sweet potatoes with heavy cream, nutmeg, salt, cinnamon, and pepper. Transfer half of sweet potatoes to prepared dish, arranging them in an overlapping pattern like shingles. Cover with apples, then remaining sweet potatoes, overlapping the potatoes as before. Pour any remaining cream over the top. Cover with foil and bake until tender, about 45 minutes. Increase oven temperature to 500 degrees F. Uncover dish, scatter bread crumbs over the top, and dot with remaining 3 tablespoons butter. Bake, keeping a close eye on the gratin in case bread crumbs start to burn, until golden brown on top, 8 to 10 minutes more. Serve immediately."^^<http://www.w3.org/2001/XMLSchema#string>
