Mary Berry's Ultimate Christmas

British baking doyenne Mary Berry celebrates her favorite time of the year, Christmas, by serving her traditional Christmas dinner to three of her friends. Before they sit down for the meal, Mary talks to chefs Angela Hartnett and Monica Galetti about their traditional Christmas meals which touch upon their Italian and Samoan backgrounds, respectively, and she visits an organic farm to try and convert her presenter friend, Rylan Clark, a notoriously picky eater, into "liking" a staple of many a Christmas dinner table, namely Brussels sprouts. Primarily, Mary provides tips for making that traditional Christmas dinner preparation as stress free as possible.
