Asma Khan grew up in India, where late summer means monsoon season. But it wasn't until she moved to England in the '90s that she learned how to cook. At 45, after earning a PhD in constitutional law, she opened Darjeeling Express. The London restaurant made her into a celebrity chef and an authority on Indian food. Now, Khan is out with a new cookbook called Monsoon, which celebrates a seasonal approach to cooking. In today's episode, Khan speaks with NPR's Asma Khalid about making a big career change in her 40s, her commitment to an all-women kitchen staff, and the meaning of modular cooking.
