Citrus butter under the skin of the turkey ensures a moist and succulent turkey, of course the flavour of the butter can vary in winter a wild mushroom butter is excellent (the butter is also delicious with chicken). A saffron glaze provides a rich colour and flavour to the bird, while the couscous absorbs its juices for a scrumptious accompaniment. The beauty of this recipe is that it is tasty served hot or cold, in hot weather it seems pure madness to have a meal of hot heavy food. Save yourself the nightmare of getting everything ready on time for your christmas dinner, prepare the meal the day before and serve a feast of cold turkey.
