Glaze: Mix all the glaze ingredients in a small bowl. Pour the mixture into a shallow bowl or baking dish that will fit the chicken thighs snuggly inside. 2 tablespoon honey + 1 ½ tablespoon soft brown sugar + 2 ½ tablespoon dark soy sauce + 3 tablespoon lemon juice + 3 garlic cloves (grated) + 2 teaspoon sesame oil + ½ teaspoon salt + ¼ teaspoon pepper Pat the thighs dry with paper towels and add them to the baking dish. Turn them several times in the mixture to coat them well all over. 4 chicken thighs Optional marinating time: 30 minutes on the counter. If marinating for longer (up to four hours), cover the dish with plastic wrap and place it in the refrigerator. Remove it from the fridge about 30 minutes before baking.
Preheat the oven to 350°F/ 180°C.
Assemble the dish: Lift the chicken pieces from the marinade using tongs, and place them in a roasting tin. Reserve the marinade.
Bake for 35-40 minutes or until cooked through, basting every 10 minutes or so with the leftover marinade and the cooking juices. Check with a meat thermometer; the internal temperature should be 165°F/74°F.
Remove the thighs from the roasting tin, place them on a baking sheet lined with aluminum foil, and keep them warm.
Preheat the broiler while you thicken the glaze.
Reduce glaze: Pour the leftover marinade and all the cooking juices from the roasting tin into a small saucepan. Reduce the glaze on medium-high heat until it thickens nicely.
Broil chicken: Brush the chicken with the glaze. Broil them for 2 to 4 minutes. Keep an eye on the chicken all the time to ensure that the skin doesn't burn under the broiler.
Rest for a few minutes before serving.
