Taiyaki is a Japanese fish-shaped cake that has now become popular all over the world. Taiyaki translates to “baked sea bream”, sea bream is the nickname of the tai fish, which is found in saltwater. Hence the fish shape of the taiyaki is supposed to indicate the “tai” fish, which represents prosperity and luck. Taiyaki is traditionally filled with a red-bean paste but it is now popular to fill these fish-shaped taiyaki cakes with chocolate, custard, icing, ice cream, cheese and even sweet potatoes. Taiyaki cakes are made with special taiyaki pans. Taiyaki should be slightly crisp on the outside, similar to a waffle and soft and light on the inside.
