KUNG PAO CHICKEN

Steps:

• Heat a large cast-iron or non-stick skillet or wok over medium. Add peanuts and 1 tablespoon vegetable oil; cook, stirring occasionally, until fragrant and golden brown in places, about 5 minutes. Transfer to a plate.
• In a bowl, whisk together 3 tablespoons soy sauce, cornstarch, and rice wine. Stir in chicken; let stand 5 minutes. Meanwhile, combine black vinegar, remaining 2 tablespoons soy sauce, sesame oil, and brown sugar in a small bowl, stirring until sugar is dissolved.
• Heat remaining 1 tablespoon vegetable oil in skillet over medium-high. Add peppercorns and chiles; cook, stirring frequently, until fragrant and chiles are blistering in places, about 1 minute. Stir in garlic; cook 30 seconds. Stir in chicken mixture, spreading in an even layer to edges of skillet. Cover, reduce heat to medium, and cook, undisturbed, until chicken is beginning to turn golden on bottoms but is not cooked through, 2 to 3 minutes.
• Stir in vinegar-soy mixture and celery. Increase heat to medium-high and cook, uncovered, stirring frequently, until chicken is just cooked through and liquid thickens enough to become glossy and evenly coat, about 3 minutes. Remove from heat, stir in toasted peanuts and scallions, and serve with rice.
