Lesley and Sara visit a Liverpool bakery using the humble loaf to re-build a shattered community, and sisters Caitlin and Freya explore how recent changes on Manchester's Curry Mile show the evolving relationship with flavour.After seeing kids increasingly targeted by food manufacturers over the eras, Harvey and Sara find out just how far novelty foods have come with a modern game that requires a very strong stomach. Jon heads back to the mill to show Harvey how Yokshire's textile heritage has used its specialisms to survive the decline of the industry. They explore how the stereotype of the Yorkshireman in flat cap has been given a modern and hugely successful twist by local hat designer Rhian Kempadoo Millar.The girls travel to Blackburn to meet Zainab Bilal, a one-woman pie business who is combining the modern love of easy fast food with this age-old favourite. Caitlin and Freya help her make a batch of 'burger pies' to explore just what it is that has made the humble pie such a winner for working families throughout history.Finally, Sara and northern chef Rob Owen Brown prepare a celebration meal for the family using cuts of meat and nostalgic flavours the family might have turned their noses up at in the past. Sara then joins Polly and the family to raise a glass to the modern legacy of the north's culinary history.
