Flavour: The potato chip story
The Food Chain
Sep 10, 2025

Self-confessed crisp lover Ruth Alexander traces the story of the crisp or potato chip, starting with a tasting experience matching fine wines and “rubbish crisps” at a wine bar in the northern English city of Manchester.

With the help of journalist and crisp historian Natalie Whittle, Ruth finds out about the commercial beginnings of the potato chip in the fine dining rooms of nineteenth century New York. She meets the chef who travels the world searching for new taste sensations to develop into a packet of crisps for snack giant Frito-Lays. Can you guess which flavours nearly, but not quite, made it onto the shelves?

Ruth also talks to salty snack expert Jolene Ng of Mintel, who researches the role crisps play in modern life. And with Japan renowned for its unusual flavours, Ruth meets Makoto Ehara, the boss of one of the country’s biggest potato chip makers Calbee, who tells her about the threat climate change poses to the future of the potato chip industry.

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.
