Coat the chicken entirely with the marinade ingredients and allow it to be chilled in the fridge for at least 3 hours.
Heat up some cooking oil in a pot till hot. Deep fried the chicken until golden brown and crispy. Drain the chicken on paper towels to soak up any excess oil.
In another pot, add the orange juice and sugar and cook on medium-high heat. Allow the sauce to boil.
Add the corn flour solution. Turn to high heat and cook till the sauce simmers and thickens.
Drizzle the orange sauce over the fried chicken from Step 2. Garnish as desired and serve immediately whilst hot.
Notes
I deep fried the chicken piece by piece to ensure the temperature of the oil does not drop too much to retain the crispiness. Also, lesser oil is needed if you cook in small batch.
