At the end of the steaming time, remove the turkey from the oven (it won’t look or smell very appealing at this point, but stay with me, because things are going to get a whole lot better soon). Change your oven setting to 350°F/180°C, convection-only (no steam), or switch to your regular oven if your steam oven doesn’t have standard oven capabilities. If you have a second oven with a pyrolytic/self cleaning function rather than a steam cleaning function, I’d recommend you switch ovens at this point anyway. Pyrolytic clean is going to make your clean-up job much easier.
Rub the steamed turkey all over with the softened butter, and put it back in the oven. Roast for 30 minutes, then brush all over with the glaze and continue roasting, brushing with more glaze every 15 minutes, until the thickest part of the bird, in the leg meat just next to the breast, reaches 73-76⁰C (163-169⁰F) on an instant read thermometer. The roasting part of cooking should take somewhere between 1 ½ and 2 hours. If the turkey is browning too quickly during cooking, cover it with a tented piece of foil to protect the skin. If the juices are starting to burn in the pan underneath the bird, add half a cup of water and check regularly to see if it needs more.
Remove the cooked bird from the oven and place it somewhere warm to rest for 30 minutes. You can cover it with aluminium foil for resting, but my preference is to cover with a sheet of baking paper and a dish towel, which will keep the heat in but allow better airflow so it doesn’t steam as it will under foil.
You’re done! Present your beautiful turkey to the waiting crowd and pat yourself on the back for a job well done. I feel very strongly that my part with the turkey is played once I’ve gone to the trouble of buying and cooking it, and I want nothing to do with the carving and serving. If you adhere to the same theory, you can give that honour to your most esteemed guest or family elder.
