To baste a turkey, you can use a variety of ingredients such as melted butter, broth, herbs, lemon juice, and poultry seasoning. Basting helps to keep the turkey moist and adds flavor, while also contributing to the browning and crisping of the skin. The frequency of basting can vary, with recommendations ranging from every 30 minutes to every 45 minutes. Some sources suggest that basting is not necessary and that a turkey can still turn out juicy and flavorful without it. Ultimately, whether to baste or not is a personal preference, and there are alternative methods, such as brining and using high heat initially to brown the skin, that can also result in a delicious turkey.
