Mix together the garlic, salt, pepper, honey, mustard and oil.
Place the wings into a sealable bag and pour in the sauce, use your hands to coat the chicken in the marinade. Place to one side for 10 to 15 minutes.
Preheat the oven to 390F / 200c.
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. Don't discard the marinade.
Place in the pre heated oven for 40 minutes. Flip halfway through.
Transfer the leftover marinade into a small sauce pot.
Mix together the cornstarch and a tablespoon of 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.
Place under the broiler for a couple of minutes to brown them up and caramelize the sauce.
Transfer the wings to a plate, and serve.
