Overview: Nigel Slater shares the flavours that for him make Christmas a truly delicious season. As we tick off the days and open our advent calendars, Nigel shows us how to cook for both entertaining and self-indulgence; filling our kitchens with tastes and smells to get us in the spirit of the season and serving up food designed to bring comfort and joy... Nigel also makes a culinary trip to Norway and goes in search of a very special Christmas tree.
