Preheat the oven to 180C fan / 200C /400F / Gas 6

Peel & cut the potatoes into quarters (around 6/7cm x 5/6 cm - no smaller), I usually allow 3-4 per person

Put into a pan of cold water & bring to the boil, parboil for a couple of minutes, insert a sharp knife into the potato (if the tip just goes in slightly then they are ready)

Turn the heat off & leave them in the water for 4-5 minutes, check them then as you need the outside of the potato to start to break down but not mushy, drain, then give them a rattle in the pan to get some good fluffy bits on the outside of the potato, sprinkle with salt.

Leave the lid off the pan & allow to cool.

About an hour before you eat pour the oil into a shallow roasting tray, put in a good slug,  I usually make sure that the base of the tin is well covered.

Put the tray in the oven to heat up for a few minutes, take out of the oven & add the potatoes, you want them to sizzle, turn them over in the oil until coated then put back in for around an hour ( turn them after 30mins) until they are golden & crispy.Enjoy!
