Bring you turkey to room temperature. Pat the turkey leg dry with paper towels make sure it is as dry as possible so it browns nicely.
You can rest it on a roasting tin whilst you prepare the pomegranate glaze.
In a small bowl, combine the olive oil, pomegranate molasses, mustard and sage.
Brush half over the turkey leg with the glaze and season with salt and pepper.
Roast the leg covered with foil. Roasting time will depend on its weight, normally it needs 1-11/2 hours at 200C/ gas mark 6.
As it is roasting, keep on checking every 15 minutes and brush over it a bit more of the pomegranate
Once ready, let it rest for 15-20 minutes
For the cranberry sauce, simply place all the ingredients into a small saucepan and bring to a gentle simmer. It will be ready in more or less 10 minutes, the cranberries will have burst and thickened.
