Taiyaki are basically just pancake batter filled with whatever. Traditionally red bean paste. This time I did red bean paste, chestnut paste and Nutella. I also really like filling them them a crème patissiere or yuzu curd if I have enough time/foresight to make it ahead. Because you cook them in the special mold, they get a nice crispy outside. People tend to have a preference for eating the head or the tail first. I personally like to go tail-first 😈
