During the Joseon era (1392-1897), the dairy cow office was relocated to a royal court ranch on Mount Naksan east of Seoul. It was renamed Tarak-saek (dairy department). Royal physicians took charge of gathering milk and making tarak-juk to present to the king. From the tenth lunar month to the first month of the next lunar year, they offered tarak-juk to the royal court. The Hall of Senior Officials also offered tarak-juk to elderly officials. Recipes for tarak-juk are recorded in the Joseon books such as Revised and Augmented Farm Management and the Women's Encyclopedia.
