Glimpses behind the scenes of two cooking shows form the core of this Boston Globe article about the not-new phenomenon of chefs marketing themselves on television. Ming Tsai tapes his PBS series on the premises of a high-end appliance distributor. Instructors and interns from Johnson & Wales prep his ingredients. Guest Jacques Pepin joins him to saute up a turkey breast and butterfish, then feast on the results with wine and champagne. Over at Joanne Chang’s restaurant kitchen, she welcomes “Ace of Cakes” star Duff Goldman who is taping a new Food Network show “Sugar High.” Crisis strikes when Chang realizes she gave too many fortune cookies samples to the crew and needs more on-air for her recipe. Goldman offers to take the blame by telling viewers that he ate them all. Things are always more perfect than reality after these cooking shows are edited for broadcast.
