Put the chicken thighs in a bowl, add the ingredients for the marinade, mix well and set aside for 30 mins.
Heat a pan on medium flame and add 1 tbsp oil and when the oil is quite hot, add the sugar. It'll melt. spread it around the pan and don't allow it to burn.
Arrange the chicken pieces in a single layer in the pan and sear for 2-3 minutes on each side. The chicken should be nicely charred and red/dark brown from the caramelised sugar. Remove from the pan and set aside.
Drain the soaked rice. Lower the flame, add the remaining 1 tbsp oil and toss in the white parts of the spring onion, ginger and garlic. Sauté for a few seconds.
Now add the rice and fry for 5 min. Then add in the soy sauces and Shaoxing wine and stir to coat the rice grains. Spread the rice in an even layer nestling the chicken thighs in.
Pour in just enough water to just cover the rice, put on the lid and turn the flame to high for a min. Then reduce the flame and let the chicken and rice simmer for 20 min.
After 20 mins, remove the lid, sprinkle with the green parts of the spring onion and serve.
