To a large stock pot or Dutch oven, add all of the ingredients; orange juice, salt, sugar, peppercorns, sage, rosemary, cloves, cinnamon sticks, star anise pods, garlic, orange slices and water.
Heat over medium heat, stirring well to help the salt and sugar dissolve well into the liquid.
Bring the brine to a boil, then promptly remove from heat. Let the brine cool completely to room temperature.
Place thawed turkey (breast side down) into a brining bag, removing any giblets and neck from inner cavity. Pour the cooled brine over the top of the turkey, including all ingredients that were cooked in the brine (herbs, orange slices, cinnamon sticks, ect.)
Seal the brining bag and secure with clips if necessary. Refrigerate the brined turkey for 18-24 hours.
Once the brining is complete, remove the turkey from the brine and bag. Discard the brine and bag - do NOT reuse.
Place several dish towels in your sink and place the brined turkey on top of the towels. Thoroughly rinse the turkey with water both in the inner cavity and on the outer skin. Lightly pat dry with clean towel and prep for roasting.
