Conchiglioni Ripieni Al Forno

(Large Stuffed Shells). (Serves 20 for buffet, 8-10 as a pasta course). In a large skillet, heat the olive oil over medium heat. Add the meat and cook, stirring, until browned. Raise the heat to high, stir in the wine, and let most of it evaporate. Lower the heat to medium, add the tomato sauce, and cook, uncovered, for 15 minutes, or until thickened. Set aside. In a large saucepan scald the milk (bring to just under a boil). Set aside. In another large saucepan, melt the butter. Whisk in the flour to make a smooth paste, and cook, stirring, for about 1 minute. Slowly whisk in the hot milk, and cook, whisking, until the sauce thickens enough to coat the back of a spoon. Stir in the salt. Remove from the heat, and stir in the ragu until well blended. Set aside. Preheat the oven to 375F. Lightly butter a 14 x 8-inch baking dish. Using a spoon, fill the shells with the ragu mixture and place them close together in the baking dish. In a bowl, combine the milk and heavy cream. Slowly pour evenly over the shells. Sprinkle the cheese over the top. Cover with aluminum foil and bake for 40 minutes. Serve immediately.
