Ingredients :

• Day-old cold rice — This is truly the one ingredient you can’t compromise on. Hot rice in the pan gives a sticky mush. Cold, the grains stay separate, they toast slightly on the surface and absorb soy sauce without falling apart. If you don’t have any, cook rice two hours ahead and spread it on a tray in the fridge to speed up cooling.
• Cooked chicken thighs — The recipe starts with already cooked chicken—thighs or breasts, depending on what you have on hand. Thighs are more flavorful and stay juicier under the sauce. Breasts are okay, but they dry out quickly if the pan is too hot for too long.
• Sesame oil — One tablespoon seems like nothing. But it’s what gives that characteristic toasted nutty note. Don’t replace it with a neutral oil—it’s not for cooking, it’s for flavor. It goes into the pan with olive oil, never alone over high heat.
• Cornstarch — Dissolved in a little cold water then added to the sauce, it transforms it completely in seconds. Without it, the sauce stays thin. With it, it becomes syrupy, clinging to the chicken. That’s the difference between a sauce that coats and a sauce that runs to the bottom of the bowl.
