Cooking dinner on Christmas Day, with its multitude of scrumptious trimmings, for a hungry gaggle of family and guests is quite a challenge, especially so when the hard-pressed cook has to make do with rather limited cooking resources.
However, a golden opportunity presents itself for those lucky enough to possess a covered barbecue – be it charcoal or gas fired – for the cook of the day to earn lots of browny points, and the unfortunate person who drew the short straw to clean the fat splattered, ex turkey oven, a welcome respite.
Barbecuing the bird will also bring several worthwhile benefits
1. Valuable oven space is freed up for other culinary duties
2. The succulence, terrific taste, beauty to the eye of the beholder and the bewitching aroma that pervades the atmosphere transcends, in my humble opinion, the impact that oven-cooked birds usually produce AND, if the turkey is smoke-cooked, the resultant golden mahogany veneer will be the propellant responsible for projecting the taste buds of all those nearby into mouth watering overdrive !
3. The oven (see above) retains its original pristine state (which is nice!)
4 After the cook has retrieved the bird, perhaps braving the elements*, and presented it for approval to the hungry throng he, or she can bask in some well deserved back-slapping hero worshiping (always good for a barbecue chefs ego).
Neither rain or snow should prevent you from using your barbecue but a cold wind whistling around the cooking area will require an extended cooking period which should be factored into your time table.
Prepare your barbecue for 'Indirect cooking'
Ensure the giblets and neck have been removed from the bird's cavity. Rinse the turkey all over with cold water, and inside its neck and body cavities. Pat dry with kitchen toweling. Sprinkle the cavities generously with salt and freshly ground pepper.
Tuck the wings behind the bird's back but leave the legs free ie not tucked into the band of skin by the parsons nose (the tail end) or tied closely together.
Use your clean hand, or a small brush, to spread groundnut oil or softened butter (margarine if you prefer) all over the bird. Lightly season the oiled surfaces with salt and freshly ground black pepper.
Carefully position the turkey , on its back, down the center of the grill, partially shielding the sides where it touches the grill bars with a double band of foil about 4” wide. Tuck one edge of the band under the bird's back to help secure it. Wrap a 2 to 3 inch wide band around each knuckle and the lower part of the legs. Position a meat thermometer deep inside the fattest muscle section of a leg. Make sure that the tip of the thermometer does not touch the bone – it will give a false reading if it does.
Cook the turkey, with the lid of the barbecue down, until the thermometer registers 185 F/100C.
For charcoal units, apart from the weather conditions mentioned above, this will vary according to the quality and burning characteristics of the fuel you are using. For example, replenishing the fire-bed part way through cooking, with fresh briquettes, will result in a marked drop in temperature. The resulting extension of the cooking period should therefor be factored in. Fortunately there are charcoal briquettes on the market with a burn duration that hopefully will enable you to tackle a large bird or joint without recourse to mid-flight refueling.
As a rough guide to cooking times (cooking at medium heat), somewhere in the region of 2 ½ hours for a 11 – 13 lb turkey whereas a 20 - 22 lb bird will cook faster per lb thus only requiring about 3 ½ - 4 hours to be fully cooked. Allow 20 – 30 minutes additional cooking time if the bird is fully stuffed* at the neck. *To make extra stuffing (there never seems to be enough!) bake some separately in a small oven-proof dish. Place the dish, or dishes, fore and/or aft of the bird (not directly over the fire bed) during the final 30-40 minutes of cooking. Leave the dishes on the covered barbecue (on low heat) whilst the turkey is settling down before being carved.
Tip: Roughly halfway through roasting the bird, turn it 180 degrees to help avoid uneven cooking.
The finale: Immediately after removing the magnificent bird from the barbecue, flaunt it (this should get the digestive juices up and running big time) before letting it rest for 20 minutes or so prior to carving.
Hickory-smoked turkey with a rich Irish glaze
A sure fire way to make your Christmas turkey look even more stunning, even more tasty is to smoke-cook it. Simply add 2 – 3 chunks, or 2 – 3 handfuls of small chips of hickory wood* to the barbecue's fire-bed (be it charcoal or gas) roughly halfway through the prescribed cooking period. Add the wood earlier if you wish to deepen the bird's color and increase its piquancy.
During the final 15 minutes or so of cooking brush the bird all over with a glaze made by beforehand by mixing roughly 2 oz of softened butter with 2-3 tablespoons of Irish Malt Whiskey. Alternatively you could use your favourite liquer...Drambuie perhaps.
