Start by cleaning the chicken. Remove any excess fat and clean it thoroughly.\n\n2. Submerge the chicken in a big pot of water. Add in the bunch of green onions and fresh ginger.\n\n3. Bring the water to a boil and then reduce to a simmer.\n\n4. Let the chicken cook for about 45 minutes or until it is fully cooked.\n\n5. Once the chicken is cooked, remove it from the pot and put it into a bowl of ice water. This helps to keep the chicken skin firm.\n\n6. Rub the chicken with salt, sesame oil, and black pepper.\n\n7. To prepare the rice, wash the jasmine rice under running water until the water runs clear.\n\n8. Heat up 2 tablespoons of vegetable oil in a pot, then add the minced garlic and minced ginger.

Once boiling, reduce to a simmer and cover the pot. Cook until the rice is done, usually takes around 15-20 minutes.\n\n11. To make the optional sauce, combine the oyster sauce, soy sauce, cornstarch water, chicken broth, and sugar in a saucepan. Stir well and heat over medium heat until it thickens.\n\n12. Now, carve your chicken and serve it over the flavorful jasmine rice. Pour some of the optional sauce over the chicken if desired.\n\n13.
