In a bowl, coat the chicken thighs thoroughly with salt, pepper, cayenne, garlic powder, baking powder, oil, and cornstarch
Heat about half an inch of oil in a pan until a wooden chopstick bubbles when inserted
Fry the chicken until golden brown on both sides
Drain the chicken on a wire rack
In the same pan (emptied of excess oil), toast the arbol chilies briefly
Pour in the whisked sauce ingredients: orange juice, sugar, vinegar, soy sauce, sambal, garlic, and ginger
Let the liquid reduce for 3-5 minutes
Stir in the cornstarch slurry to thicken into a glossy glaze
Toss the crispy chicken back into the pan to coat
Serve
