As a kid, chef Maneet Chauhan traveled India by train, and her favorite part of the journey was always all the snacks she got to sample along the way. It's what inspired her recent book, "Chaat: Recipes from the Kitchens, Markets, and Railways of India: A Cookbook," and the starting point for Christopher Kimball's conversation with Chauhan on Milk Street Radio (listen here). Get a taste of Chauhan's book in this video and read more here. #milkstreetvisits
