Remove the turkey from the refrigerator one hour before preparing.
Coat the inside of the turkey and under the skin with butter and thyme. Massage well to thoroughly permeate the flesh.
Coat the outside of the turkey with the butter without the thyme. Massage the flesh well with the butter.
Stuff the turkey, pushing the stuffing towards the bottom. You can use a binder needle to sew the cavity. I use wooden skewers to hold the two sides together. It doesn't close the cavity, but it holds it in place.
Tie the two legs together. Pass a rubber band under the rump, then over the tied legs, and wrap it around the turkey's wings.
Place the trimmed turkey in a deep baking dish (about 3 cm / 1.2 inches high). Set it aside.
Bake for 3 hours and 30 minutes without preheating the oven.
Cook the turkey on one side (wings) for 30 minutes, then place it on the other side and cook for a further 30 min. Baste twice with its juice during cooking.
Add water as soon as you see that the cooking juices have run down. Don't let it burn. Add 1 glass of water each time (150 ml/ 5 oz).
Turn the turkey onto its back and continue cooking, basting occasionally with its juices.
Baste turkey with cooking juices
check for doneness by poking a skewer between the thigh and the breast. The juice that comes out must be clear.
Once the turkey is cooked, remove and cover with a double layer of aluminum foil. Leave for 20 minutes before serving.
