This week on Cooking Issues, the Curious Cook Harold McGee joins Dave and Nastassia in the studio to talk cocktail sauce, the Impossible Burger, the New York Botanical Garden's Amorphophallus titanum or "corpse flower," to wash or not to wash chicken, scalding milk, and more. Plus, an on-air tasting (and smelling) of assorted nuts and seeds, and the latest dump meal report from Natty Lopez.
