There are two techniques that can help:
Brining: Brining involves soaking the turkey in a solution of salt, sugar, and water. This process helps to keep the meat moist and flavorful. Brining should be done for at least 12 hours before cooking.
Basting: Basting involves brushing or spooning melted butter, oil, or broth over the turkey while it cooks. This helps to keep the meat moist and adds flavor.
