Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly oil it to prevent sticking.
In a small bowl, whisk together honey, soy sauce, Sriracha, rice vinegar, minced garlic, grated ginger, and sesame oil until well combined.
Pat the drumsticks dry with paper towels. This helps the glaze stick and the skin crisp. Place them on the prepared sheet in a single layer.
Brush half of the glaze over the drumsticks, turning them to coat both sides. Reserve the rest of the glaze for brushing later.
Bake for 20 minutes. Then flip the drumsticks, brush with the remaining glaze, and return to the oven for another 10–12 minutes, or until the internal temperature reaches 165°F (74°C) and the glaze is glossy and caramelized.
If you like extra color and crackly edges, broil for 1–2 minutes at the end, watching closely so they don’t burn.
Remove from the oven and let rest a couple of minutes. Sprinkle with toasted sesame seeds and sliced scallions before serving.
