Taiyaki - fish shaped pancake

Taiyaki, fish shaped pancake with bean jam filling, is very popular sweets you can find in Japan and one of my most favorite traditional Japanese sweets. The bean jam filling is called An or Anko, which I'm addicted to, and it's used in many other traditional Japanese sweets such as Dorayaki (disk shaped pancakes sandwich with Anko in between). Although Anko is the most popular filling for taiyaki, you can find other fillings like custard, chocolate cream and matcha cream. But I want you to try the Anko one. In western countries, beans are supposed to be savory but sweet beans are good too !
