Nigella's turkey breast with Christmas stuffing recipe

A moist roast turkey with a spicy Christmas stuffing. You need to go to a butcher to get a whole breast joint and you need to ask for it to be butterflied and boned and make sure the skin is left on. I know it might sound a bit of a faff, but take it from me that stuffing a whole double-breast joint is very much easier than stuffing and rolling a single breast joint, as is more commonly found in supermarkets.
