In this healthy roast turkey recipe, brining keeps the turkey moist and a homemade bay-spice mix gives the turkey amazing flavor. Diced celery root or parsnip adds flavor and texture to the gravy. A heritage, natural or organic turkey, without added sodium solution (found in most conventional turkeys), tastes best in this recipe. If you have a conventional bird, just skip the brining (Step 1). The recipe that's included for Bay Spice Blend makes 1 cup; if you want to skip the step of making the spice blend, you can substitute Old Bay Seasoning.
