Deck the halls, stuff the turkey and break out the Christmas fizz as four of the most memorable celebrities from past series come back to compete in two festive-themed challenges, hosted by MasterChef judges Gregg Wallace and John Torode.Competing this year are musician Mel Blatt, actor and comedian Richard Blackwood, singer Duncan James and reality star Faye Winter. None of them took the trophy first time around, so they are back to battle it out to and see who can take home the title of Celebrity MasterChef Christmas Champion and the ultimate Christmas present – the much-coveted Golden Whisk trophy.Some Christmas sunshine is guaranteed in the first challenge, as the celebrities are tasked with creating a dish that is reflective of Australia during the festive season. Each has their own recipe to follow and a set of ingredients, which are found in their Secret Santa mystery box. For this merry occasion, the celebrities must present their Australian Christmas dish not only to John and Gregg, but also a truly special invited guest – one of Australia's greatest exports and national treasure, Peter Andre.Next, the celebrities are challenged to cook their ultimate Christmas dinner using well-known seasonal ingredients. They can be as creative as they like, but the celebrities will need to deliver a Christmas cracker of a two-course menu, packed with passion, personality and a punch of yule flavours that will knock the festive socks off the judges. Expect fireworks, and maybe a sprinkling of fairy dust, as all four celebrities fight to sleigh the competition in a bid to take the title and be crowned Celebrity MasterChef Christmas Champion 2023.
