Grayson and Philippa Perry are joined by TV presenter Sue Perkins, who crafts an unusual work of art on the subject of food. Grayson also talks to Rose Wylie, who became an art world star in her seventies. There's a peek inside the studio of Lucy Sparrow, who uses felt to create colourful replicas of everyday food items, while comedian Mawaan Rizwan makes his own piece of food-related art. Plus, special guest Nigella Lawson helps choose the favourite public art submissions of the week.
