The Chemistry of Food & Taste | Dr. Harold McGee

About this video

Food scientist Dr. Harold McGee explains the chemistry behind why foods taste as they do and how small preparation choices change flavor. Huberman introduces Dr. McGee’s work on how cookware, bowls, pans, and utensils alter taste, and how a pinch of salt added to bitter foods including coffee changes its chemistry and flavor for the better. Dr. McGee recounts researching egg-white foams and finding cooks recommended a copper bowl for whipping meringue or souffle, which led him into the chemistry literature on eggs. They discuss meat preparation and umami savoriness produced by heating proteins in specific ways, polyphenols in chocolate and cacao, and whether expensive wines truly taste better or reflect marketing. Dr. McGee also describes experimenting with his own tea bushes, varying withering, drying, and manipulation to produce different teas, and discusses tannic flavor in tea and coffee.
