Dry the wings very well with paper towels.

Combine the baking powder, salt, and garlic powder. Rub mixture on the wings.

Place wings on a rack on top of a foil lined baking sheet. (Optional: for extra crispy wings let rest in the refrigerator for at least 8 hours or overnight.)

Combine the butter, sriracha, and honey in a sauce pan and heat over medium heat until bubbly. Combine the lime juice, soy, and cornstarch in a small bowl and stir until the cornstarch is dissolved.

Add cornstarch mixture to the sauce and cook for a minute or two until the sauce thickens. Turn off heat.

Bake wings in a 450 degree oven until golden brown, crispy, and cooked through, about 50 minutes, depending on the size of your wings, flipping the wings half way through the cooking time.

After wings are crispy and golden brown, remove from the oven and turn the broiler on high.

Brush the tops of the wings with some of the sauce and broil for a minute or two, watching carefully, until the sauce just starts to caramelize and the wings turn brown in some spots.

Remove the wings from the oven and toss with the remaining sauce.

Garnish with sesame seeds and spring onion.

Serve immediately.
