Clean the chicken drumsticks thoroughly.
Heat cooking oil in a pan and sear the drumsticks on medium heat until golden brown on both sides.
Mix soy sauce, sugar, cooking wine, minced garlic, pepper, and water to make the sauce.
Pour the sauce over the golden-browned drumsticks and bring to a boil.
Simmer on medium-low heat, turning occasionally, until the sauce thickens.
Serve the finished braised chicken drumsticks on a plate.
