I made this cake this weekend for the small cake competition here on base. I got 3rd place. This cake was all about Okinawa. I made the cherry blossoms, the kokeshi doll and the Okinawan inspired fan from fondant. My filling was Beni Imo also known as the Okinawan Sweet Potato. It is purple. I am thrilled with how it turned out. It is exactly as I planned.
