01 - In a large stockpot, combine cold water, apple cider, kosher salt, brown sugar, black peppercorns, allspice berries, and bay leaves. Bring to a boil, stirring until the salt and sugar are fully dissolved.
02 - Incorporate cranberries, orange slices, garlic, onion, rosemary, and thyme into the pot. Simmer for 5 minutes, then remove from heat.
03 - Allow the brine to return to room temperature. To expedite cooling, add 2–3 cups of ice if desired.
04 - Place the thawed turkey into a large brining bag or food-safe container. Pour the cooled brine over the turkey, adding additional cold water if required to fully submerge the bird.
05 - Seal or cover the container and refrigerate for 12–24 hours, turning the turkey once or twice during brining for even flavor absorption.
06 - Remove the turkey from the brine, discard the liquid, rinse the turkey thoroughly under cold water, and pat completely dry with paper towels. Continue with your preferred roasting method.
