For a turkey gravy that really tastes like the bird but doesn't require drippings, we began by making a full-flavored turkey stock that included not just the neck and giblets but also some excess skin and fat from the turkey—powerhouse sources of turkey flavor. We started our untraditional method for making turkey stock by simmering the neck, giblets, and trimmings in chicken broth in a Dutch oven (chosen instead of a saucepan for its greater surface area); doing so efficiently extracted flavor-packed juices and fat from the parts that browned and formed a rich fond once the liquid evaporated. We then sautéed chopped carrot, celery, and onion for aromatic depth; deglazed the pot with white wine; added more chicken broth; simmered the stock (covered to prevent evaporation) for about an hour; and strained out the solids. We didn't defat the stock, since the aromatic compounds in the bird's fat contributed a significant amount of turkey flavor. Then, to turn the stock into a gravy, we made a roux by toasting flour in melted butter and whisking the stock into the roux.
