Cut the chicken into bite sized pieces, sprinkle with sake and leave for 10 minutes. Dust with the cake flour and katakuriko, and deep fry in oil. I coat the chicken in flour by putting them in a plastic bag and shaking it.
Put all the seasonings in a container and mix together.
Put the combined seasonings in a heated pan with the fried chicken pieces, and mix together until the chicken is coated and glossy.
When the fried chicken pieces are nice and glossy, it's done. You can eat a mound of vegetables with the sauce on the chicken.
Story Behind this Recipe
This is the deep fried karaage version of "Chicken simmered with lemon" (Recipe ID: 1644593) which is usually not deep fried! I've simplified the flavoring ingredients too. Guys seem to prefer the deep fried version.
It's easy, and great for bentos. If you coat the chicken in flour the night before, it's easy to finish up in the morning. When you're coating the chicken with the sauce in the pan, if you cook it for too long the sauce will boil away, so be careful not to let that happen.
