Wash the potatoes and cut into wedges.
Put the potatoes wedges into a saucepan of salted boiling water, for 5mins, then turn the head off and leave to stand for 5mins covered with a lid.
Drain the potatoes and leave out in a single layer on a clean tea towel to cool completely.
Preheat the oven to 220ºc/Gas 7. Grease a baking tray with olive oil and heat in the oven for 5mins.
Meanwhile, in a small bowl combine the salt, pepper, chilli flakes and paprika.
Place all the wedges in a mixing bowl, pour over the spices and mix until all covered.
Tip the potatoes onto the hot baking tray and bake in the oven for 20mins, turning over halfway through. Once crispy and cooked through, serve immediately.
