Perfect oven baked potato wedges

I've been meaning to tell you (the image is four years old) my way of getting perfectly cooked potato wedges with minimal effort. 

You cut them (to roughly the same size). 

You cover them in oil, salt and pepper. 

You then arrange them so that the only thing touching the baking sheet is the potato skin.

You then put them in the oven (at 225 °C) and wait until they are perfect.

You do not stir them. They will not stick to the sheet. And they will all be cooked to the same level of perfection. 

You are welcome!
