Follow these steps to make these wings come to life in your kitchen:

1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. In a small saucepan over medium heat, combine pineapple juice, soy sauce, brown sugar, rice vinegar, garlic, and ginger. Bring the mixture to a simmer, stirring occasionally.
3. In a small bowl, mix the cornstarch and water until smooth. Gradually whisk this into the saucepan. Continue to simmer the sauce until it thickens, about 5-7 minutes. Remove from heat and stir in the sesame oil.
4. Arrange the chicken wings on the prepared baking sheet. Brush them generously with the pineapple teriyaki sauce, reserving some for later.
5. Bake the wings for 25-30 minutes, flipping them halfway through, until they’re golden brown and cooked through.
6. Once baked, brush the wings with the remaining sauce and sprinkle with chopped green onions and sesame seeds.

Remember, it’s okay if things get a little messy—that’s part of the fun of home cooking!
