Takoyaki is a popular Japanese street food made from a batter of flour, eggs, and dashi (a type of broth). The batter is cooked in a special molded pan, creating small, round balls. Each ball is typically filled with diced octopus, green onions, and pickled ginger, giving it a savory flavor. Once cooked, takoyaki is often topped with takoyaki sauce, a sweet and savory sauce, and drizzled with mayonnaise. It is usually garnished with bonito flakes and aonori (seaweed flakes) for added taste. This delicious snack is enjoyed at festivals and food stalls throughout Japan.
