The Food Chain
Mar 25, 2017

In our second and final episode on the humble spud, we meet the people who see the global economic future as being potato powered.

The potato is the world's most produced staple food after rice, wheat and corn - yet historically, it was seen as the root of filth, misery and obesity. In our previous episode we heard how over time it came to be used as a tool of power by the state, to create a healthy and robust workforce. This week, food historian Rebecca Earle, tells us that history is repeating itself in China, which is now the world's biggest producer of potatoes.

China's central government sees the potato as key to food security, but it's got some work to do to produce a cultural shift away from rice. We'll be serenaded by one of the country's potato champions, the operatic 'new farmer' Sister Potato, who says she is changing hearts, minds and cuisine with her songs. Then we'll head to the streets of Beijing to gauge enthusiasm and ask can the spud shake off its lowly reputation?

Africa and developing countries have the biggest predicted growth in potato production in the coming decades. But is the world in danger of putting all its spuds in one basket? We’re asking whether the potato is the answer to food security or if the vegetable’s patchy history doomed to repeat itself.

Plus we head to Peru to visit the scientists protecting thousands of varieties of potato, and meet the man who ate nothing but potatoes - for a year.

Can music change the way food tastes?

Music is part of the backdrop to millions of meals every day. But what if it is doing more than simply creating atmosphere?

In this episode of The Food Chain, Rumella Dasgupta explores the growing evidence that sound can shape the way we experience food and drink. From scientists studying how the brain combines hearing and taste, to chefs designing dishes around playlists, we ask whether music has become an ingredient in its own right.

Chef Gaggan Anand explains why music sits at the centre of his restaurant in Bangkok, where sound, lighting and food are carefully choreographed into a single experience. Cognitive neuroscientist Ophelia Deroy shares research showing how music can influence our perception of sweetness, bitterness and texture, and explains why flavour is far more than what happens on the tongue.

We also hear from Ola Sars, founder of the business music platform Soundtrack, whose company helps restaurants, cafés and hotels tailor the music they play. He shares research suggesting that the right soundtrack can influence customer behaviour and even affect sales.

But not everyone is convinced. Dan Keeling, co-owner of London's Noble Rot restaurants and a former music industry executive who signed artists including Coldplay and Lily Allen, explains why he has chosen not to play music in his dining rooms at all.

From silent restaurants to carefully curated playlists, from neuroscience labs to commercial dining rooms, we explore the increasingly important role sound plays in the way we eat.

The business of food tours

Food tours are becoming one of the fastest-growing parts of the travel industry, with tourists increasingly choosing to explore cities and cultures through what they eat.

In this episode, Ruth Alexander explores the global rise of guided food experiences and the people building businesses around them.

In Manchester, food tour guide Julia Fairburn takes Ruth through some of the city’s best-known food spots, explaining how successful tours combine local history, storytelling and carefully paced eating experiences designed to leave visitors with lasting memories.

Eric Wolf, founder and executive director of the World Food Travel Association in Valencia, Spain, explains how food tourism has expanded worldwide into a multi-billion-dollar industry, as travellers increasingly seek authentic and immersive culinary experiences.

We also hear from Judith von Prockel, who began creating holidays centred around food experiences more than two decades ago, long before culinary tourism became mainstream. She reflects on how attitudes towards food travel have changed and why people are increasingly planning trips around what they want to eat.

And in Malaysia, Pauline Lee from Simply Enak describes the work involved in creating memorable food tours in a growing and increasingly competitive market, where guides must balance logistics, hospitality and cultural storytelling alongside the food itself.

From hidden local gems to global tourism trends, we explore why food tours have become big business — and what travellers are really looking for when they book them.
