Add the potatoes to a large pan of salted simmering water and continue to poach for 10 to 15 minutes.

Once the potatoes are cooked, lift out of the pan with a slotted spoon and leave them to air dry on a cooling wire.

Whilst the potatoes are cooling, add the oil to a large roasting tray and pre heat the oven to 200°c.

Place the tray into the oven for the oil to heat up.

Once the oil is hot, carefully add the potatoes.

Put the tray back in to the oven and roast for a good 25 minutes before turning.

Then cook for another 20 minutes until golden and crispy.

Once cooked remove from the tray and season with flaky salt.
