In a large pot, heat apple cider with the salt and sugar, whisking until the salt and sugar are fully dissolved, about 10 minutes.
Remove from heat and pour into a large container or brining container.
Bring to room temperature. (This can be done by placing in the fridge)
Once cooled, add the apple cider vinegar, garlic, spices and herbs, orange zest and slices.
Place the turkey in the brine and add just enough water to cover the turkey.
Cover the container and place in the fridge for 8 to 12 hours.
Remove turkey from brine and pat dry with paper towel or kitchen towel.
The turkey is now ready to roast, bake, smoke or BBQ.
