Kung Pao Chicken (Gong Bao Ji Ding)

Cut the chicken thighs into 2 cm cubes, aiming for uniform size so they cook evenly in the wok. Combine with the cornstarch, soy sauce, and Shaoxing wine in a bowl. Toss thoroughly until every piece is coated in the thick, slightly sticky marinade. This is the 'velveting' technique — the cornstarch forms a protective coating that prevents the chicken from overcooking and drying out during high-heat stir-frying, and creates a very faint, smooth skin that catches the sauce. Let it rest for at least 20 minutes at room temperature. The soy and wine will begin to penetrate the surface of the chicken, and the cornstarch will fully hydrate. Do not refrigerate for this short marinade — cold chicken going into a hot wok drops the wok temperature dramatically and steams rather than sears. While the chicken marinates, mix the sauce in a small bowl: combine the soy sauce for sauce, black vinegar, and sugar and stir until the sugar dissolves. Set aside. The sauce should taste aggressively sour-sweet-salty, since it will be diluted by the wok's heat and the chicken's juices.

Heat the neutral oil in your wok over medium-high heat until it begins to shimmer and you can see faint wisps of heat rising from the surface — about 175°C. Add the whole dried Sichuan chilies and the Sichuan peppercorns together. They will immediately spit and crackle. Stir continuously and briskly with a wok spatula for 20–30 seconds. This is the blooming stage: the dry heat extracts the fat-soluble capsaicin from the chilies and the hydroxy-alpha-sanshool (the numbing compound) from the peppercorns into the oil, perfuming the entire cooking medium with mala (numbing-hot) flavor. The chilies should deepen from bright red to a dark, brick-wine red — not black. The peppercorns will turn a darker, more fragrant shade. Your kitchen will immediately fill with a sharp, throat-catching, floral chili vapor. This is normal and desirable: it means the oil is absorbing the flavor.

Working quickly — kung pao is a high-speed dish and every second matters. Into the chili oil, add the garlic, ginger, and scallion sections and stir-fry for 15 seconds until fragrant. Raise the heat to maximum. Add the velveted chicken in a single layer and let it sear undisturbed for 60 seconds — you need the high heat to develop a faint crust on the cornstarch coating. Then stir-fry vigorously, tossing constantly, for another 2–3 minutes until the chicken is just cooked through. Test by cutting a cube — the center should be white with no pink. Pour the pre-mixed sauce (soy, vinegar, sugar) around the edges of the wok where it will hit the hottest surfaces and caramelize slightly as it enters the dish. Stir everything together for 30 seconds. Pour the cornstarch slurry in a thin stream around the edges, tossing as you pour, until the sauce tightens and clings to the chicken. Remove from heat. Add the roasted peanuts and toss once. The peanuts go in last to preserve their crunch. Serve immediately over steamed white rice.
