In a large bowl or ziplock bag, place the garlic, ginger, soy sauce, apple cider vinegar, sriracha and honey and mix well.
Add the chicken wings to the marinade and coat them with the marinade. Cover the wings and place in the fridge for 10 minutes.
Preheat the oven to 390ºf / 200ºc.
Place a large cooking rack on top of a large rimmed baking tray.
Once the wings are ready, place the wings on the rack, leaving space between each one and place in the pre heated oven for 40 minutes. Transfer the marinade into a small sauce pot.
After 20 minutes, flip the wings over so they cook evenly.
Mix together the cornstarch and water in a small bowl.
5 minutes before the wings are ready, put the marinade on a high heat and bring to the boil. As it is boiling, add the cornstarch and water mix to the sauce and stir until it has thickened.
Take the wings out of the oven and baste them with the thickened sauce.
Transfer the wings to a plate, sprinkle over sesame seeds and sliced green onion and serve.
