After 10 minutes, place the duck in a skillet then season with 3 tablespoons of minced garlic, ginger, lemon grasses, and bay leaf.

Once it is boiled, reduce the heat and cook until the water is completely absorbed into the duck.
Remove the duck from heat and set aside.
Preheat a frying pan over medium heat and pour olive oil into the pan.
Once the oil is hot, put the cooked duck in the frying pan and fry until both sides of the duck are lightly golden brown.
