For brine: Pour salt, sugar, peppercorns, coriander seeds, cloves, thyme, rosemary, bay leaves, orange peels, apple cider, and vegetable stock into a large pot and simmer until salt and sugar dissolve, about 15 minutes. Allow mixture to sit until completely cooled. Stir mixture into ice water. If using brining bag, place turkey into bag and pour brine over turkey. Seal and place in refrigerator overnight. If using bucket, place turkey into bucket, breast side down, and pour brine over the bird. Place in refrigerator or a cold, dry place (if it doesn’t fit in the refrigerator) overnight (adding 2 to 3 cups of ice to the mixture every 4 hours if turkey sits out overnight). Remove turkey from brine, pat dry and place onto the rack of a roasting pan. Discard brine.
