We wondered, though, if tradition has it right, so we ran a few tests.EXPERIMENTWe roasted three turkey breasts (which we chose over whole turkeys to minimize variables) in 350-degree ovens until they reached 160 degrees. One breast we left in the oven undisturbed to act as a control. The second we roasted in another oven and basted every 20 minutes. The third we didn’t baste, but we opened and closed the oven door every time we basted the second breast to evaluate the effect of simply opening the door. We weighed all three turkey breasts before and after cooking to determine the percentage of moisture lost and recorded the total cooking time. We also roasted three whole chickens (again, easier to manage than whole turkeys) under the same circumstances and compared the level of browning.RESULTSThe total cooking time was 59 minutes for the control, 66 minutes for the unbasted breast exposed to the opening and closing oven door, and 69 minutes for the basted breast. Most important, the moisture loss of all three was comparable, ranging from 22.4 to 24.0 percent—a statistically insignificant difference—and tasters found all the birds comparably moist. In terms of browning, the basted chicken was evenly bronzed, while the other two exhibited slightly lighter, less glossy browning that was also a bit patchy.EXPLANATIONBasting purportedly keeps meat more moist by cooling the surface and thus slowing down the rate at which the meat cooks. And the more gently the meat cooks, the juicier it will remain. Basting did slow the cooking down more than just opening and closing the oven door but not enough to make a difference in moisture loss. In terms of browning, the drippings used for basting contain a lot of fat and protein, which encourage browning because they provide some of the starting materials (amino acids) for the Maillard reaction.TAKEAWAYBasting not only makes a negligible difference in moisture loss but also prolongs the cooking time and requires more hands-on work. For a really juicy turkey, we prefer a more hands-off approach such as brining or salting, which not only helps turkey retain moisture but also seasons the bird. And while basting did improve appearance, we don’t think the difference is significant enough to make it worth it.America's Test Kitchen is a real 2,500 square foot test kitchen located just outside of Boston that is home to more than three dozen full-time cooks and product testers. Our mission is simple: to develop the absolute best recipes for all of your favorite foods. To do this, we test each recipe 30, 40, sometimes as many as 70 times, until we arrive at the combination of ingredients, technique, temperature, cooking time, and equipment that yields the best, most-foolproof recipe.Each week, the cast of America's Test Kitchen brings the recipes, testings, and tastings from Cook's Illustrated magazine to life on our public television series. With more than 2 million viewers per episode, we are the most-watched cooking show on public television.http://www.americastestkitchen.comMore than 1.3 million home cooks rely on Cook's Illustrated and Cook's Country magazines to provide trusted recipes that work, honest ratings of equipment and supermarket ingredients, and kitchen tips.http://www.cooksillustrated.comhttp://www.cookscountry.com
