Is the culture of professional kitchens shifting?

In recent weeks, one of the restaurant world’s most influential figures stepped down amid allegations about his conduct at work. It’s been widely reported that former employees accused René Redzepi, founder of Copenhagen’s Noma, of creating a toxic working environment involving verbal and physical abuse. Redzepi has since apologised publicly, saying he has worked to change.

Ruth Alexander uses this moment as a starting point to explore a broader question: what is, and what should be, the culture inside professional kitchens?

For many chefs, stories of gruelling hours, intense pressure and explosive tempers have long been part of the industry. But are those conditions still the norm today, or is a different kind of kitchen culture beginning to take shape?

Ruth is joined by three chefs from different generations and parts of the world, each reflecting on their own experiences of coming up in the industry, and how those experiences have shaped the way they run their kitchens now.

Jun Tanaka, chef-owner of Michelin-starred restaurant The Ninth in London, looks back on starting out more than three decades ago. Preeti Mistry, executive chef at Silver Oak in California, shares her perspective after 25 years in the industry. And Manon Fleury, head chef at Datil in Paris and co-founder of an organisation working to prevent violence in kitchens, explains why she believes change is both necessary and possible.

They discuss whether the old hierarchies and harsh environments are being left behind, what a healthier kitchen culture could look like, and what still needs to change.

Rethinking the potato

Potatoes are having a moment.

Once dismissed as dull, stodgy or even unhealthy, they’re now back, appearing on restaurant menus, in food magazines and across social media feeds.

But the story of the potato goes back much further.

In this episode, Ruth Alexander traces the journey of one of the world’s most familiar foods. From its origins millions of years ago to its place in today’s global food system.

AJ Shehata, senior sous chef at Fallow restaurant in London explains why the potato forces chefs to get creative.

At the Natural History Museum, botanist Sandy Knapp explains how the potato may have been born from a chance encounter between two wild plants in the Andes, an event that made it possible for potatoes to grow underground and spread across new environments.

We explore how the potato became a global food. Potatoes USA president Blair Richardson explains how demand continues to grow worldwide, and how the industry is working to reshape the potato’s image.

We ask whether the potato’s reputation is deserved. Nutrition scientist Candida Rebello shares research suggesting potatoes may be far more beneficial, and more misunderstood, than many people think.

And at the International Potato Center in Peru, scientist Julian Soto works with farmers to conserve thousands of native potato varieties. In the Andes, potatoes are not just a crop, they are part of culture, identity and family life.

From ancient origins to modern revival, this is the story of how the potato conquered the world, fell out of favour, and is now being rediscovered, just as new challenges begin to emerge.
