Celebrate the festive season with the perfect dusting of Mary Berry's very own Christmas magic. In a one-off television treat, Mary opens her kitchen to some of TV's best-loved faces as they join her in cooking delicious party dishes especially for her Christmas party. With varying degrees of nerves, skill and determination, but tons of excitement, Alex Jones, Fearne Cotton, Darcey Bussell and Adil Ray take turns to join Mary beside her stove. The One Show's Alex Jones is determined to show off her family's special recipe for rissoles, while Darcey Bussell takes a break from the Strictly judging panel to find herself under the spotlight when tasked with trying to create the perfect ballet-inspired Christmas dessert. Adil Ray, screenwriter and creator and star of Citizen Khan, tries to impress with some very precise canapes, while Fearne Cotton is determined to show Mary that her delicious seasonal stuffed squash could be the party's winner. With even more delicious Christmas dishes to be made between them, from the table's centrepiece - a stunning ginger-glazed ham - to perfect squash, brie and cranberry tarts, moreish herby blinis and a magnificent white chocolate cherry and brandy cake - the pressure is on for Mary and her cooking celebrity helpers to bring together a party table festive enough for all of Mary's guests. To top it all off, classically trained pianist and singer Myleene Klass joins the celebrations and can't resist tickling the ivories on the house piano, inspiring a chorus of impromptu carol singing.

Mary Berry loves Christmas more than any other time of year - it's about spending time with family and friends, but mostly it's about helping others to cook! This holiday season Mary opens her kitchen to four eager if somewhat nervous celebrities - Huw Edwards, Dina Asher-Smith, Eleanor Tomlinson and Joe Lycett - all hoping to fine-tune their festive cookery skills. Mary teaches them some of her mouthwatering Christmas recipes that are perfect for entertaining across Christmas week and even on the big day itself. On the menu are Mary's pan-fried halloumi with fresh tomato chutney, crispy salmon and dill filo parcels, a chicken-and-mushroom suet pie, a peppered fillet of beef with brandy sauce and perfect potato and squash roasties, and for the sweet tooth in us all, a hazelnut meringue roulade with white chocolate and clementines, and a limoncello trifle.
