Scottish chef Tony Singh travels to India, the country of his ancestors, to trace his family roots and discover whether his mum's Punjabi cooking is the real deal. He begins his journey in Amritsar, which is draped in lights for the festival of Diwali, before braving the treacherous Grand Trunk Road to Delhi, a place Tony has only ever visited twice. Along the way, he fulfils a boyhood dream to meet the Nihang, nomadic Sikh warriors whose cooking techniques are legendary. He receives an exclusive invite to eat and cook with a Maharaja and, as his waistline tightens thanks to the rich Punjabi diet, he burns off the calories at Bollysweat, the fitness phenomenon taking Delhi by storm. As Tony gets under the skin of Punjabi ways, he discovers how the Sikh religion and the region's troubled past have created a food and culture like no other. He ends his epic adventure at the ancestral home in Delhi, where his 93-year-old uncle Ameer opens a window on his family history he will never forget.

Rick Stein is in Australia, a country he fell in love with on his first visit at the age of 19. On a journey in search of the ingredients revolutionising Australian cooking, Rick sets off from his new home in Mollymook, New South Wales, up to Sydney before flying to Tasmania. In Sydney, Rick revisits some of his old haunts and reminisces over his misspent youth, a time when he was fleeing a personal tragedy back home. In the fish market, where his love affair with Australian fish culture began, Rick learns that a staggering 70 per cent of fish eaten in the country is imported. Now, after years of looking to other countries for its ingredients, Australia is beginning to look to its own produce, and the most modern move on the culinary circuit is to go ancient. Rick travels out to Botany Bay - the site of James Cook's first landing. There, he gets back to basics, does some foraging and learns the art of cooking the aboriginal way. But when it comes to cooking with native foods, the sleepy backwater of Tasmania is leading the way. Tasmania is not only an emerging foodie destination but, as Rick discovers, an eco-paradise. He goes hunting for wallaby (the latest wild meat taking Sydney by storm), samples the best single-malt whisky in the world and tastes sustainably farmed salmon that has become a national obsession. With small-scale producers making a splash on the international food scene, this wild outpost has also become a great business model for a new - sustainable - kind of industry.

MasterChef judge and meat connoisseur John Torode fulfils a lifelong ambition to go to Argentina, where eating beef is a national obsession. After savouring the street food from the barbecues, or 'asados', in Buenos Aires, John embarks on an epic road trip that takes him across the vast pastures of the pampas to Mendoza in the foothills of the Andes. His mission - to find the best piece of steak in the world and the best way to cook it. Along the way, John discovers that modern industrial farming has changed the landscape of the legendary pampas and threatened a way of life unchanged for centuries. In order to learn the traditional ways of rearing cattle, he goes native with the gauchos on a working estancia and experiences one of the most authentic barbecues he's ever had. Back on the road, when John stops at a truckers' cafe to have lunch, he has an epiphany. He grasps the secret of cooking with fire. His final destination is a fabled restaurant in Mendoza, where cooking beef has become an art form. It's here, among the restaurant's seven fires, that John learns his final lesson.
