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 round balls filled with diced octopus, green onions, and pickled ginger. Once cooked, Takoyaki is typically brushed with a savory sauce, sprinkled with bonito flakes, and topped with mayonnaise. This delicious snack is often enjoyed at festivals and food stalls, showcasing the unique flavors of Japanese cuisine.
