Perfect roast potatoes

Preheat the oven to 200C/180C Fan/Gas 6.
Put the potatoes into a pan and just cover with water. Add a tablespoon of salt, cover with a lid, and bring to the boil. Boil for 15 minutes, until cooked (they will slide off when pierced with a knife). Drain thoroughly in a colander, then set the colander on top of the cooking pan and cover the potatoes with a tea towel. Set aside for 10 minutes to steam dry.
Meanwhile, put the vegetable oil, dripping, or duck fat into a roasting tin and heat in the oven for 10 minutes.
Gently toss the potatoes around a little in the colander. Tip the potatoes into the tin of hot fat and give it a shake to spread the potatoes out in the pan, but don't worry about turning them. Put the tin into the oven and roast for 20 minutes. At this point give the potatoes a turn and then return them to the oven for a further 20-30 minutes or until golden and crunchy. Season the potatoes with salt and pepper and serve.
