Remove the giblets from the turkey cavity. Preheat your grill or smoker to 250 degrees (or whatever temperature you are cooking the turkey at).
Place the giblets in a foil pan along with half of the herbs, 2 cloves of garlic, and 2 cups of turkey stock. We typically then place the foil pan beneath the turkey we are smoking to catch any additional drippings from the smoked turkey. Alternatively, you can just smoke the giblets for about an hour.
To make the turkey stock for this giblet gravy recipe add the smoked giblets and turkey neck to a small pot or sauce pan along with about 2 cups of water or turkey stock. Reserve the liquid and turkey drippings from the pan the giblets were smoked in. Bring the liquid to a boil, then reduce to a simmer and add the herbs and garlic. Cover and simmer for about 1 hour.

Remove the neck and giblets from the turkey gravy stock. If desired, you can finely chop the smoked giblets and return them to the gravy or you can omit them for a smoother gravy. Add in the turkey stock/turkey drippings and stir to combine.
Thicken the gravy, if needed, with a flour or cornstarch slurry, adding the slurry a little at a time.
