Charles is a professor of experimental psychology at Oxford University, the author of Gastrophysics: The New Science of Eating, and the head of the The Crossmodal Research Laboratory, which explores the interactions between senses when we experience flavour.  Charles also won the 2008 Ig Nobel Prize for Nutrition for his work on the 'sonic crisp'. On the episode we discuss the evolution of flavour, the differences between taste and flavour, how our tongues and noses work, learned flavour associations, the impact of sound, texture, temperature, colour and weight on flavour perception, the tongue map, imagined flavour, Louis Cheskin and how corporations manipulate flavour through shape and packaging, 'sonic seasoning', desserts that make you cry, hairy cutlery and much, much more.
