What are the secrets behind your favorite foods? Why are some treats — like chocolate chip cookies — delectable, while others — like cookies made with mealworms — disgusting? You might think you understand what makes something sweet, salty or bitter, but David Pogue gets a taste of a much more complicated truth. Not only is our perception of taste far more complex than we imagine, involving all our senses and even our memories, but once we master the secrets of flavor, it's easy to fool unsuspecting taste buds. Could food scientists help us enjoy our food more — without packing on the pounds? NOVA scienceNOW explores the neuroscience of taste to discover how the "flavor magicians" perform tricks on our senses. Pogue will also venture into America's Test Kitchen, where a Thanksgiving dinner is diced, sliced, dissected and put under the microscope. Viewers will meet Nathan Myhrvold and his team of chefs, who are using advanced lab equipment to cook up dishes that look and taste like nothing else, revealing in dazzling visual detail the physical and chemical changes that take place in food as it cooks. www.pbs.org/nova/sciencenow
