Method
Cut the potatoes lengthways into fairly even wedges. Leave the skin on.
Soak them in cold water for 20–30 minutes if you have time. This removes some surface starch and helps them crisp.
Drain and dry extremely well.
Toss with olive oil, salt and black pepper.
Preheat your air fryer to 180°C.
Air fry pointed side up at 180°C for 15 minutes, turn.
Increase to your air fryer's 230°C maximum and cook another 5 minutes. Turn to remaining side
Air fryer at 230°C and cook another 3 minutes.
Taste before adding any more salt, since the KFC gravy or what ever sauce you have may already be quite salty.
