Slice the potatoes finely. This recipe does not work as well if the potatoes aren't really thin. You should almost be able to see through them. I recommend using a slicer or a Mandoline if you can.
Bring a pan of water to the boil.
Add the sliced potatoes and cook for 3-5 minutes, depending on thickness. You don't want your potatoes to go like mush.
Drain and leave them to steam in the colander for a few moments.
Lay them out on a baking sheet, giving them plenty of room.
Leave them to dry for at least 20 mins longer if you can. The drier the potatoes, the better crisp they will have.
Spray generously with Frylite and lightly season.
Place them in the oven, rotate them at regular intervals, and season them again halfway through to your taste.
Remove once crisp and golden brown, and season again if needed. Total cooking time should be between 20 -35 minutes.
