5 lb/2 kg medium sized potatoes (sounds a lot, but believe me they will all be eaten) 4 Tbsp olive oil
Bring a pan of salted water to the boil. Peel the potatoes and cut into chip shapes. Place in the boiling water. Once the water returns to the boil. cook for 4 minutes. Drain well and transfer to one or two roasting trays. It doesn't matter if the chips start to crumble at the edges, as this will give you the nice crunchy bits during cooking. Toss in the olive oil and a good pinch of flaked sea salt and spread out in a single layer. Bake in the oven for about 40 -45 minutes, turning a couple of times throughout, until golden and crispy.
