Newsreader Huw Edwards, sprinter Dina Asher-Smith, Poldark star Eleanor Tomlinson and comedian Joe Lycett join Mary to prepare dishes for a festive get-together. On the menu are pan-fried halloumi with fresh tomato chutney, crispy salmon and dill filo parcels, a chicken and mushroom suet pie, a very indulgent peppered fillet of beef with brandy sauce and potato and squash roasties, while desserts include a hazelnut meringue roulade with white chocolate and clementines, and a limoncello trifle.
