On this Valentine's Day edition of Eat Your Words, host Cathy Erway is joined by Simran Sethi, a journalist and educator focused on food, sustainability and social change. She is also the host, writer and creator of The Slow Melt, a podcast that uses chocolate as the thick, delicious lens through which to explore the world—from flavor and physiology to chemistry and conservation, from global markets and gender to climate change, social justice and beyond—highlighting the people, places and processes behind this $100 billion industry.
