Dame Merry Berry knows a thing or two about cooking up a festive feast, and this year she is sharing her cooking skills with three novice cooks, cousins James, Jack and Leah, who want to throw a spectacular surprise feast for their respective mums and bring together their whole family for the first time in two years. With Mary's help, can they pull it off and give their mums a Christmas surprise they will never forget?

Mary has also enlisted the help of Alex Jones and Patrick Grant. While Mary focuses on getting the novice cooks up to speed in the kitchen, Patrick and Alex oversee the extras that will make this Christmas reunion special. They are also on hand to offer moral support when temperatures rise in the kitchen.
