Another great recipe from Mark Bittman. It’s almost a given that time and oven space are at a premium on Thanksgiving Day, and this method of roasting turkey, unorthodox as it is, addresses both. Split, flattened, and roasted at 450°F (lowering the heat if the bird browns too fast), a 10-pound bird will be done in about 40 minutes. Really. It will also be more evenly browned (all of the skin is exposed to the heat), more evenly cooked (the legs are more exposed; the wings shield the breasts), and moister than birds cooked conventionally. But it works only for relatively small turkeys.
