For centuries they remained a secret deep within the jungles of South America. But now a quarter of the world’s people enjoy chilies or other peppers every day, and chili powder is the most popular spice on the planet. This video explores the unique and powerful qualities packed inside the humble pepper, from its distinctive flavor to its incendiary kick to its potential health benefits. Viewers learn nutritional facts—for example, many peppers contain more vitamin C than an orange—while a jaunt through history explains why the British Parliament revolted when asked to forgo their fiery fix. The program also features chef Paul Merrett’s take on peppers, from spicy Thai curry to the classic Italian supper dish, pepperonata with scallops. Produced by the Open University.
