Place a 2-gallon zip-top plastic bag in a big bowl (the bowl gives structure to the bag and prevents all the liquid from spilling all over your counter if not careful). If your turkey is too big, stores now carry “turkey brining bags that you can buy.
Add water to the bag then the salt and sugar. Stir mixture with a wooden spoon until blended. Add the apple cider, crushed garlic, fresh thyme, fresh parsley and scallions.
