Making the Marinade: In a medium bowl, mix soy sauce, vinegar, sake, fish sauce, sugar, chopped garlic, salt, pepper, and white sugar. Stir until sugar is all melted.
Marinade the Chicken: Take chicken thighs and place them in a mixing bowl. Pour 2/3 of the marinade over the chicken and make sure each piece is fully coated. Cover the bowl with saran wrap and place it in the refrigerator. Allow the chicken to marinate for a minimum of 30 minutes… preferably marinate the chicken overnight for the flavors to fully infuse and achieve an even yummier taste!
Cook the Chicken: Heat a large dip pan over medium high head, drizzle generously with cooking oil. Place the chicken thighs in for 7 minutes before flipping them over, skin side down. Repeat the process twice.
Pour the Sauce: Pour the remaining marinade into the sauce pan to coat the chicken. Reduce to medium low heat and simmer for approximately 15 minutes.
Garnish and Serve: Garnish the chicken with chopped green onions and cilantro. Serve over a warm bowl of rice... drizzle delicious adobo sauce over the rice! (Feel free to add a fried egg on top.)
