What is "takoyaki"?

Takoyaki is a popular Japanese street food that consists of small balls of batter that are filled with diced octopus, tempura pieces, and green onions, and then cooked in a special molded pan. The balls are flipped with a skewer until they are crispy on the outside and fluffy on the inside. Takoyaki is typically served with a variety of toppings such as takoyaki sauce, mayo, and bonito flakes, and is often enjoyed as a snack or a light meal. Takoyaki is a staple in Japanese street food culture and can be found at food stalls and festivals throughout Japan.
