The biggest appeal of this pudding is undoubtedly its unique flavor, created by the unexpected combination of soy sauce and pudding. It is made by blending double-brewed soy sauce from the historic Wakamatsu Miso & Soy Sauce Shop in Minamisoma City with milk from the long-established Matsunaga Milk dairy brand . When the lid is opened , the rich aroma of soy sauce immediately fills the air. The pudding itself has a smooth texture and a deep, rich egg flavor, with the soy sauce and puddling blending perfectly to create an entirely new and unforgettable taste experience.
