1 tbsp cornstarch β mixed with water to make slurry
2 tbsp water
scallions β sliced (for serving)
Instructions
Pat the chicken dry, then place in a bowl. Whisk the egg with 1 tbsp of the soy sauce and pour over the chicken; toss to coat and let stand 10 minutes.
In a shallow bowl, combine the all-purpose flour, 0.5 cup cornstarch (for coating), baking powder, kosher salt, and black pepper. Dredge the marinated chicken pieces in the mixture, pressing to adhere; shake off excess.
Heat the vegetable oil in a wok or Dutch oven to 350Β°F over medium-high heat. Fry the chicken in 2β3 batches until golden and cooked through, 3β4 minutes per batch (internal temperature 165Β°F). Transfer to a wire rack or paper towels to drain.
Carefully pour off the frying oil, leaving 1 tbsp in the wok. Add the garlic, ginger, and red pepper flakes; stir-fry until fragrant, 30β45 seconds.
In a bowl, whisk the orange juice, orange zest, remaining 3 tbsp soy sauce, rice vinegar, granulated sugar, and sesame oil. Pour into the wok and bring to a simmer over medium heat, stirring to dissolve the sugar, 1β2 minutes.
Stir together the 1 tbsp cornstarch and the water to make a slurry. While the sauce simmers, drizzle in the slurry, stirring constantly, until the sauce is glossy and thick enough to coat a spoon, 1β2 minutes.
Add the fried chicken to the sauce and toss until evenly coated and heated through, 30β60 seconds.
Serve immediately, topped with sliced scallions (for serving).
