Takoyaki, literally fried or grilled octopus, is a popular ball-shaped Japanese dumpling or more like a savory pancake made of batter and cooked in a special takoyaki pan. It is typically filled with diced octopus, tempura scraps (tenkasu), pickled ginger, and green onion.
Nowadays, it is commonly brushed with takoyaki sauce and mayonnaise, and topped with green laver (aonori) and katsuobushi (shavings of dried bonito). There are many variations to the takoyaki recipe. For example, ponzu i.e. soy sauce with dashi and citrus vinegar, goma-dare i.e. sesame-and-vinegar sauce or vinegared dashi.
