1. Marinate breast meat or drums (deboned) with 1 tbs sugar, 1 tbs mirin, 1 tbs cooking wine, 2 tbs light soy sauce, 1 tsp dark soy sauce, 1 tsp sesame oil for at least half an hour.
2. Dust chicken with corn flour and saute till lightly burnt (Use little oil, or no oil if drums still have skin on them; I used some sesame oil).
3. Pour remaining marinade over chicken and cook till sauce thickens.
4. Cut into pieces (optional) and serve hot with steamed rice.
