The chilli revolution of the past decade has made the UK a nation of chilli-jam lovers, and windowsill spice-growers. But our desire for the fiery kick of heat-giving food goes back centuries. What is it about us that makes us crave the pain and pleasure of chilli, wasabi, and horseradish?

In this programme Sheila Dillon investigates our love for the hot stuff, speaking to chefs, growers, and researchers who are taking heat to new, extravagant heights.
