In a large mixing bowl, add the wings, oil and the salt. Combine well.
Spray the air fryer / racks with some oil and warm up the air fryer at 200 C / 392 F.
Air Fryer with Racks (oven type)
Spread the chicken wings out evenly on the racks and cook with the fan on for 20 - 25 minutes at 200 C / 392 F. (Depending how crispy you like your wings)
Take them out and let them rest on a cooling rack until needed.
Air Fryer with a Basket
Put all the wings in the basket and cook for 20 minutes at 200 C / 392 F. Move the wings around every 10 minutes by taking the basket out and giving it a very good shake.
After 20 minutes, take the wings out of the air fryer. Put a single layer of wings back into the air fryer and cook for another 5 minutes at 200 C / 392 F or until crispy. Repeat until all the wings are done.
Let them rest on a cooling rack until needed.
Making the Sticky Glaze
Optional Step. Put 1 teaspoon of sugar into a cold small pot. Heat the pot up on medium and allow the sugar to form a caramel.
In a small bowl, add water, fish sauce, lime and vinegar.
As soon as the caramel comes to colour (if doing this step), add in the sauce mix and the 3 tbsp of sugar. Mix with a spoon until the sugar and caramel is completely dissolved.
Cook for 7 - 8 minutes on medium setting and then take off the heat. Check the glaze for taste and texture. Adjust according to your preferences. Be very careful since it very hot!!!
Put the wings into a bowl and toss in the glaze or serve the wings on a plate with the glaze poured over the top.
