1. Mix all the maple butter ingredients in a bowl and set aside. You can prepare this ahead of time and allow it to soften before use.
2. Preheat oven to 165°C. Remove the turkey from its packaging, pat dry, and loosen the netting slightly. Spread the maple butter all over and under the skin.
3. Roast for 1½ hours, then increase the temperature to 180°C and continue roasting for another 45 minutes, until the internal temperature reaches 70–72°C.
4. Remove from the oven, cut off the netting, and cover the turkey with foil. Let it rest for 15 minutes for carry-over cooking to complete.
5. Slice and serve with gravy, cranberry sauce, and your favourite festive sides.
