Prep the wings: Pat the chicken wings completely dry with paper towels. Add to a bowl and drizzle with olive oil. Toss to coat.
Season the wings: Add salt, black pepper, cayenne pepper, garlic powder, five spice powder, brown sugar, cornstarch, and flour. Mix until evenly coated.
Heat the oil: In a wide pan, add enough oil to cover the bottom (about 1-2 inches). Heat over medium heat.
Fry the wings: Place wings in the pan in a single layer (don’t overcrowd). Cook for 8–10 minutes per side. Turn occasionally until golden brown, crispy on all sides, and fully cooked through. Work in batches if needed.
Drain: Remove wings and place on paper towels or a rack to drain excess oil.
Make the Sauce: In a bowl or directly in a saucepan, add: minced garlic, chopped chives/green seasoning, soy sauce, honey, oyster sauce, grated ginger, salt, sugar, red pepper flakes, chopped hot pepper (if using), water. Stir everything together until well combined.
Cook the Sauce: Place the saucepan over medium heat and bring the mixture to a gentle simmer. Let it cook for 2–3 minutes, stirring occasionally, until the garlic becomes fragrant and the flavors start to blend.
Finish & Garnish: Add the fried wings to the sauce and toss until fully coated, and garnish with chopped garlic and chives.
