- Preheat oven to 425˚F. Place a wire cooking rack on a parchment paper lined baking sheet. In a medium mixing bowl, whisk together cornstarch, gochugaru powder, ground ginger and garlic powder. Blot chicken wings with paper towel and place into bowl. Toss with hands to coat.
- Transfer wings to prepared pan and bake for 25-30 minutes.
- While wings cook, whisk together ingredients for sauce in a saucepan over medium-low heat. Once simmering, reduce heat to low and simmer for 3-4 minutes, until sauce has thickened. Turn heat off and set sauce aside.
- Remove wings from oven and cool for 3 minutes to allow skin to crisp. Toss wings in a large bowl with ¼ cup of teriyaki-pineapple sauce. Serve hot with remaining sauce for dipping and sprinkle with sesame seeds and green onions.
