About this episode
You can now listen to Food Chain starting on Thursdays, so to welcome new listeners, we’re offering up some of the best bits of our award-winning programme exploring the culture, science and economics of everything you eat. Could you survive at sea for two months on a small raft, relying on your wit to feed you? Steven Callahan did just that. But he had some difficult choices to make when the fish became his only friends. It's no secret that there is a fierce rivalry between Ghana and Nigeria over who makes the best jollof rice. Singer Sister Deborah talks to The Food Chain about the history of the dish - and what the redness of your jollof says about your culinary skill. Plus we revisit Chinatown and its chequered history. From Johannesburg to London, the BBC’s Dan Saladino, explores Chinatowns around the world, and hears about the attitudes Chinese workers encountered when they first set up shop in the US.
