Preheat your oven to 210 C/ 425 F. Line a baking sheet with aluminum foil and place a rack on top. In a bowl, toss the chicken wings with salt, pepper, and oil.
Step 2
Arrange the wings on top of the rack. Transfer the baking sheet to the oven. Bake for 15 minutes.
Step 3
While the wings are cooking, prepare the sticky sauce by whisking the soy sauce, vinegar, water, minced garlic, ginger, sesame oil, honey-flavored syrup, and xanthan gum in a saucepan. Place the pan over medium heat and bring to a simmer. Let the sauce thicken, then take it off the heat.
Step 4
Take the baking sheet out of the oven and flip all the wings. Return to the oven and bake for another 20 minutes until cooked through. Transfer the wings to a large bowl.
Step 5
Pour the sticky sauce over the chicken wings and toss. Slice the scallions and add them to the chicken. Toss again.
Step 6
Transfer the wings to a large serving platter or 4 individual plates. Sprinkle with more scallions and sesame seeds. Serve immediately.
