In this episode, architectural specialist Evelyn Day constructs a metre-high white chocolate fairy castle for a girl's fourth birthday party. She has her work cut out shaping six towers alongside doors, windows, turrets and flags, a task that's all the more difficult with white chocolate as it's softer than dark or milk, and Evelyn's using a massive eight kilos of the stuff! In Yorkshire, Ashley McCarthy makes a detailed four-poster chocolate bed complete with six mattresses, floral curtains and a sheep, commissioned by a mattress company for the Furniture Makers' Charity Ball In Basingstoke, Laura Miller is asked to make something chocolate for a mental health awareness event. She comes up with a chocolate head with thoughts expressed in chocolate speech bubbles. Then she cuts out a section of the pristine-looking head, as she attempts the tricky challenge of recreating a section of brain in chocolate.
