In a saucepan, incorporate all the ingredients with a whisk.
Bring the liquid to boil, Once boiled, chill it on an ice bath for around 30 minutes.
Once solidified, remove the ginger and blend with a hand blender until smooth. Reserve.
Part B - Takoyaki
Whisk together all the wet ingredients except for the chuka idako.
Slowly introduce the dry flour into the liquid and whisk until smooth.
Pass through a sift and pour into a beaker.
Heat up the Takoyaki mould and start greasing with enough cooking oil.
Pour the batter until it fills up the sphere, followed by adding in the chuka idako. With a skewer start tilting the batter until a ball is formed. Add more batter if needed.
Once a ball is done, introduce a little bit more of oil and cook until it's evenly brown.
As a suggestion, serve the Takoyaki with a Japanese Mayonnaise, Katsuobushi, Spring onion and the Yaki Sauce.
