Ruth Alexander explores the origins and evolution of the humble grab-and-go food the burrito, which started life in northern Mexico, before crossing over into the US and becoming a hit around the world.

Versions of the spicy wrap can be enjoyed in restaurants, street food shacks and supermarket home meal kits all over the world.

We explore the burrito’s contested origins, find out why some Mexican food purists dislike the popular menu item and ask what the future holds for it, and the cuisine more broadly.

Cows emit greenhouse gases when they eat, which contributes to global warming. But is it possible to produce meat in a climate-friendly way?

Grace Livingstone visits a carbon neutral certified ranch in Uruguay, where farm manager Sebastian Olaso shows her around. She also meets Javier Secadas, a small farmer who raises cattle on natural grasslands, and agronomist Ignacio Paparamborda, from the University of the Republic in Montevideo.

Grace hears from Pete Smith, Professor of Soils and Global Change at the University of Aberdeen, and Dominik Wisser, Livestock Policy Officer, from the United Nations’ Food and Agriculture Organisation.

She tries to find out if it is possible to produce meat in a way that is both good for nature and the climate. Or whether we need to stop eating meat to cut emissions.

Why eat with your hands?

Many food cultures around the world eat using hands, and most of us use our hands some of the time. Do we really need cutlery or chopsticks to eat a salad, peas or rice? And if you were to tackle soup or stew with your hands, how would you go about it?

Michael Kaloki reports from Nairobi, Kenya, where the staple dish ugali, made from maize flour, is traditionally eaten by hand. Michael has observed that people increasingly use cutlery to eat the dish, and he speaks to restaurateurs and customers about why that might be, and what might be lost.

Ruth Alexander learns about the etiquette of eating by hand with food writer and consultant Karen Anand in India. And Ruth explores whether food might be more enjoyable, and even taste better, when eaten by hand. Psychologist Professor Charles Spence from Oxford University, and chef Jozef Youssef of Kitchen Theory in the UK share their research.

Stunning cakes, colourful salads and intricate garnishes use flowers to entice customers, but there’s more to this trend than just beautiful social media pictures.

Many cultures around the world have eaten flowers for centuries, and some of them pack a serious punch.

Devina Gupta explores the history of edible flowers and visits a site in the UK where they’re grown all year round. She gets quite a shock when trying one particular variety.

We find out why flowers are used on food nowadays, and how generations of knowledge about their use and properties were lost when they were brought to Western countries.

Do you know how much salt you should be eating?

And if I tell you it’s less than 5 grams a day, do you know how much that is?

Ruth Alexander explores the wonder of salt and why chefs think their job would be pointless without it and why the impact it’s having on the food might surprise you.

Professor Paul Breslin tells us about the “magical” chemical reaction happening on your tongue when you eat salt, and why your brain responds to that.

We hear about what eating too much salt can do to you from an expert in Australia, as well as a mother in Kazakhstan who cut out salt almost completely – in a country which has one of the highest consumptions in the world.

Over two million people work in the international shipping trade, and they are often at sea for months at a time.

That’s a lot of meals being made by the cook on board, and their work is crucial for keeping the crew happy.

Ruth Alexander hears from seafarers about why that makes “cookie” the most important person on board a ship and why, in some cases, crew members are going hungry.

A former captain of merchant vessels tells us how food is used for so-called “facilitation payments” to corrupt officials, and why crews can sometimes be powerless to stop port officials filling up suitcases with food from the ship’s stores.

We also hear about international efforts to try to tackle corruption in ports and increase welfare standards for seafarers.

What’s the secret behind the on-screen chemistry shared by some TV chef duos?

The recent death of Dave Myers, one half of ‘The Hairy Bikers’ with Si King, has prompted this programme celebrating successful food friendships. Dave and Si made food shows and cookbooks that took their fans all over the world, and off-screen they were close friends.

In this programme Ruth Alexander speaks to two chefs who have found success in food with a good friend.

Ruth Rogers, co-founder of The River Cafe restaurant in London, talks about her partnership with the late Rose Gray, who died in 2010. Together they presented ‘The Italian Kitchen’ for Channel 4 in the UK in 1998.

Italian chef Gennaro Contaldo talks about his long friendship and work with the late chef Antonio Carluccio, and the TV series they made together for the BBC, ‘Two Greedy Italians’ in 2011 and 2012. Gennaro also talks about his friendship with the chef Jamie Oliver to whom he’s been a mentor.

These are tough times for restaurants. If the pandemic's rolling lockdowns were not bad enough, independent eateries now find themselves caught on a conveyor belt of crises: inflation, labour shortages and high rents. That is without mentioning the post-Covid agoraphobic “hermit consumer", who prefers to hunker down indoors than splash the cash on going out.

If the stats are to be believed 60% of restaurants fail in the first year, 80% after five. And yet despite the long odds many are still seduced by TV dramas like The Bear into turning their passion for cooking into a business. We hear from some of the best in the business for a steer on how to keep this labour of love alive.

David Reid speaks to leading restaurant critic Jay Rayner, culinary specialist Ashley Godfrey, top chef Joseph Otway and restaurant operations manager, Sam Wheatley as they lift the lid on the trade secrets they have accumulated from years on the restaurant front-line. The programme also asks what a world without independent restaurants would be like and what we as strapped consumers can do to save the flagging middle of the restaurant market from going under.
