This looked so fab on his Christmas TV special. I am making it for christmas lunch this year, and a few other of the recipes provided. Cannot give a guarantee that it will be as brilliant as it seems, but fingers crossed it is. I'll post the recipe for the stuffing too, but I guess you can use any favourite recipes for stuffing you like if you want to. Make the butter and apply the night before cooking. The amount of butter required will depend on the size of the bird. For a 6 kilo turkey, around 150g-200g is used. approx 30 minutes per kilo on 400 plus 20 minutes at the end. Preparation time based on preparing the butter, spreading it, and packing the turky with stuffing. No refridgeration time, or stuffing prep. Cooking time based on a 5-6 kilo turkey.
