01 - Whisk together flour, eggs, dashi stock, soy sauce, and salt in a mixing bowl until smooth and thin consistency is achieved. Set aside.
02 - Preheat takoyaki pan over medium heat. Lightly oil each well to prevent sticking.
03 - Pour batter into each well, filling completely to the top.
04 - Place one piece of octopus, small amount of tenkasu, pickled ginger, and green onion into each well.
05 - Cook for 1-2 minutes until edges begin to set and golden color forms.
06 - Use skewers or chopsticks to rotate each ball 90 degrees, allowing uncooked batter to flow out and form spherical shape.
07 - Continue turning every 1-2 minutes until balls are golden brown and crisp on all sides, approximately 8-10 minutes total cooking time.
08 - Remove from pan and serve immediately. Drizzle with takoyaki sauce and mayonnaise, then sprinkle with aonori and katsuobushi.
