Sushi cake. Egg rolls are fondant covered pieces of cake and so is the sushi and hand rolls. My sister and her friend are always making egg rolls and my sister wanted me to do a simple birthday cake for her friend. I can't do simple...it is not in my repetoire...so I did SUSHI CAKE... The saying on it says " SoShe say you 40....Sounds Fishy!...then some chinese characters..
