We returned to the Cúirt Literary festival in Galway a few weeks ago for a chat about food trends with David Sax. David is the Canadian author of The Tastemakers: Why We’re Crazy for Cupcakes, But Fed up with Fondue and we talked at length about the business of food trends, what’s behind them and who decides what we eat and how we eat it. Many thanks to Dani and her team at Cúirt for all their help with this.
