Taiyaki is made using regular pancake or waffle batter which is poured into a fish-shaped pan on each side, top with desire filling before closing the pan. The batter is then cooked on both sides on medium heat until golden brown.
Morinaga pancake premix is one of my favourite brand when comes to premix choice. It has a few packaging from 2 - 4 individual sachet per pack or in box form. I love those that are individually packed as to prevent wastage and freshness of the premix. Each sachet can make about 4 pieces of standard size pancake or 5 - 6 Taiyaki with fillings.
