This week, Rob and Dave Nicholson visit the oldest sweet shop in the world on a quest to find out more about a famous Yorkshire confectionery — Yorkshire Mixture, a mix of traditional boiled sweets that's been popular for almost 200 years. The boys then journey to South Yorkshire and get to make their very own pear drops — which are a part of Yorkshire Mixture and a favourite of their dad Roger — before enjoying a taste test of their sweets back home with dad. At Eden Camp, a Second World War military museum on the outskirts of Malton, north Yorkshire, 24-year-old Summer O'Brien is in the final stages of completing a special exhibition that reveals the remarkable role the camp played in post-war Yorkshire. Eden Camp once held German, Romanian and Polish prisoners of war, many of whom, after the war, stayed on and became much loved members of the community. On the outskirts of York, we meet architect Stephen Potts who helped lead the team that restored the stunning Holgate Windmill, making it the oldest fully operational windmill in the country. Today, the team have their work cut out as they race to fulfil a big order from a local artisan baker. And in the industrial heartland of South Yorkshire, a region renowned for iron and steel works, artist and potter Steve Booton is up against it as he plans an ambitious show with daughter Janna that will showcase the very best work of 54 potters from all over the country.
