This week on Cooking Issues Dave conferred with science-of-food guru Harold McGee, author of The Curious Cook, On Food and Cooking and frequent contributor to a myriad of publications, food-related and otherwise. Together the dynamic duo solved a heap of listener queries ranging between the high and the low tech; the science behind and perceived taste of carbonation was discussed, the process of measuring meat marbling via ultrasound was explored, and the tricky art of keeping herbs fresh was touched upon. Plus that now familiar stand-by of new school cookery, sous vide, was discussed at length. This episode was sponsored by Acme Smoked Fish: a mainstay in New York’s culinary landscape for over 55 years. Guest Harold McGee
