" Who knew that specialty food producers from bastions of Americana as Gainesville, Florida, and Louisville, Kentucky, had begun to experiment with artisanal soy sauce? According to a prominent food magazine, the Kentucky producer even aged its sauce in old bourbon barrels for an added whiff of smoke and local color. Top chefs all over America were raving about the depth of flavor the smoky sauce brought to dry-aged filet mignon and buttery black cod. An avant-garde chef in Chicago had infused the soy sauce into butter. The resulting concoction was spread on bite-sized brioche, topped with tobiko caviar, and served as the amuse bouche to his seventeen-course tasting menu. "
