While the chicken bakes, prepare the ginger, garlic, scallions, and remove the chiles from their packaging. Mix the remaining sauce, reserving 1/2 tablespoon of the sesame oil, ingredients in a bowl.
Add the 1/2 tablespoon of sesame oil the a large skillet over medium-high heat. Once hot, add the scallions, garlic, and ginger. Cook until fragrant, about 1 minute.
Add the chiles and cook for another 30-60 seconds before adding the liquid ingredients.
Continue cooking over medium-high heat, stirring often, until the sauce thickens. This will take about 5-7 minutes, just in time for the chicken to come out of the oven.
Reduce the heat to low and toss the baked chicken in the sauce before removing from the heat, topping with more scallions, sesame seeds, and serving with rice, steamed broccoli, or your choice of pairings.
