The remote, isolated Kingdom of Bhutan measures its economy on Gross National Happiness. In Bhutan butter is important for both cooking and ceremonial purposes. Will visits a small farm to see how the locals churn butter by hand and samples the local cuisine before being invited to visit one of the oldest monasteries in this devoutly Buddhist country, where he lights candles to guide the souls of the dead. After sampling a cheese and chilli dish, Will travels high into the Himalayas for a lesson in how to milk a yak. He makes cheese the traditional way, in a smoky mountain hut, before enjoying a game of archery with his hosts.
