Marinate in Koji (Shio-Koji) is one of the best way to receive benefit from Koji. ( I believe )
When I eat this marinated in koji chicken karaage (Tatsuta age) first time,
I was so surprised how soft and yummy it was.
What you need to do is just marinate chicken in Shio-koji over night.
This one step makes so much difference of your Karaage or Tatsuta age!!
Then marinate in Shio-Koji for over night or for 1 day. Preparation – done!
Start cooking ! Pour soy sauce.
Deep fry them in oil until it becomes golden colour.
(Oil temp : 170 – 180°C)
