In this final episode, Nigel and Adam look at Britain's heritage foods - the old favourites still on our shopping lists today - and how the way they are cooked and who eats them has changed over the years. With pigs having historically provided food for British families all year round, and with every county in the country still rearing pigs, pork in its many forms, from ham to bacon and sausages, is the most popular choice of meat in the world. So how do farmers meet our demands for pork? The boys discover by rearing their own three different breeds of pig. As the series draws to a close, Adam takes to the markets to sell off the produce to raise funds for Children In Need.
