Jamie continues his super-food journey around the world. His travels take him to Sardinia, where he's amazed by rare local pasta and the skills needed to create it.

Jamie makes a splash foraging for the freshest seafood with South Korea’s mermaids of the sea, and visits a Swiss family’s treasured orchards to find out why an apple a day might just keep the doctor away.

Jamie marvels at the Swiss’ willingness to wild swim in freezing Alpine lakes, joins a Sardinian fishing family for a freshly-caught lunch at sea and is completely stunned to meet the oldest woman in Korea.

Jamie gets up close with cows in the Swiss mountains and hears how Alpine grass makes all the difference to their prized milk. In a Sardinian family’s vineyard, he learns how the hot days and cold nights make for an unusually healthy wine.

On the sunny island of Sardinia, Jamie meets a tomato-farming family, proud of a special tomato that’s so tasty it needs no salt.

Jamie sees how ubiquitous the sesame seed is in South Korean cooking when he tucks into their barbecue black pork delicacy, and in Switzerland he heads into the world of Willy Wonka, exploring the country’s premier chocolate factory.
