To baste a turkey, roast it for 30 minutes, and use a spoon, cup or baster to pour the basting liquid, such as stock, wine, butter, oils and gravy, over the turkey. You can also use the juices from the turkey. Cover the turkey again, and put it back in the oven for 30 more minutes. Baste the turkey every 30 minutes until it is cooked, however, use the juices from the bottom of a pan instead of other liquids.
It is best to put a small rack at the bottom of a roasting pan, and place the turkey on it. This way the juices won't touch the turkey, and the meat won't get too soft.
As a basting alternative, make a foil tent over the turkey. This keeps the turkey juicy, and you won't have to check it every 30 minutes.
Another method is to put some apple juice into a spray bottle and spray the turkey with it. For a more savory touch, infuse the apple juice with honey, herbs or butter.
As an alternative, fry some bacon, and use its juices for basting. Chop up the bacon, and sprinkle it over the cooked turkey.
After the turkey is done, make sure to keep the juices. You can use them as a gravy base or as a dressing for stuffing, vegetables and potatoes.
