In this edition of "Food Skills," we head to NYC's Robataya, where chef Yu-Jin Tsugehara gives us a master class in the art of Japanese robatayaki. Popularized in the Sendai region of Japan, the traditional cooking method features seasonal skewers grilled over a special charcoal called bincho-tan. The chefs command a central hearth, and are surrounded by a bed of fresh seafood and vegetables. At Robataya, the preparation is as memorable as the meal.
