"[Photographs: J. Kenji Lopez-Alt] Crispy chunks of deep-fried battered chicken in a sweet, sour, and savory glaze with complex orange flavor. The Chinese take-out classic, made in your own kitchen. Why this recipe works: * A balanced sauce has plenty of vinegary kick to balance out the cloying sweetness that most restaurant versions have. * Cooking the aromatics for the sauce at a lower temperature lets their flavors develop without having to superheat your wok or skillet. * We add vodka to our chicken coating. Its higher volatility and ability to inhibit gluten formation leaves you with a superior crisp crust. * Adding some of our marinade to our dry coating mixture creates little nuggets of coating that cling to the chicken pieces, adding more surface area for extra crunch. Note: Shaoxing wine can be found in most Asian markets. If unavailable, dry sherry can be used in its place. If you can't find boneless skinless chicken thighs, you can debone them yourself using this guide. Dried orange peel can be found at Chinese grocers, or make your own by peeling off sections of orange peel with a vegetable peeler and placing on a wire rack set in a rimmed baking sheet in a 275° oven until mostly dry, about 45 minutes...."
