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 and drain 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
