How to Make It
Preheat the oven to 500°. Line a large baking sheet with foil and spray with vegetable oil. In a bowl, mix the flour with the salt, Sichuan peppercorns and five-spice powder. Add the chicken and toss to coat. Spread the chicken on the baking sheet in a single layer and spray with vegetable oil. Roast the chicken for 45 minutes, turning once or twice, until browned and crispy.
In a bowl, whisk the hot sauce with the butter, soy sauce, honey and ginger until combined. Add the chicken wings to the sauce and toss. Sprinkle with the scallions and serve.
