1. Marinate chicken with garlic, ginger, mirin, soju, soy sauce, salt and black pepper. Let that marinate in the fridge for at least an hour.
2. Make the seasoned flour by combining flour, potato starch, ginger, garlic, onion, and red pepper powder, salt, and baking powder.
3. Take 1+1/4 cup of seasoned flour and combine it with water and 1 egg.
4. Dip marinated chicken in wet mix making sure to let any excess drip off then dredge it in the seasoned flour.
5. Deep fry the chicken in batches. The first fry will be at 350°F for 10-12 minutes. Let the chicken rest for 5 minutes while you raise the temperature to 375°F. Deep fry the chicken for a second time for another 3 minutes until golden brown.
6. Deep fry rice cakes for 4 minutes. Make sure to be careful because they will make the oil splatter.
7. Toss the chicken in a liberal amount of Funtable Garlic Soy Sauce and enjoy.
