What’s the recipe behind some of the world’s most-successful partnerships? Why do some flourish while others fail disastrously? In their dual memoir, “Black, White and The Grey: The Story of an Unexpected Friendship and a Beloved Restaurant,” co-owners Mashama Bailey and John O. Morisano detail how a Black chef from Queens and a white media entrepreneur from Staten Island built an award-winning restaurant in Savannah, Ga., called The Grey. Theirs is a masterclass on building a company while bridging biases on race, class, gender and culture in the heart of the Deep South. In this episode of the podcast "The Next Chapter" by American Express Business Class, Bailey, Morisano and the host Cardiff Garcia explore the coveted ingredients needed to forge a powerful alliance.
