10 Maris Piper potatoes (approx one per person), peeled and quartered
A few sprigs rosemary
Sea salt and black pepper
Heat the oven to 180 C.
Pat dry the potatoes with a clean tea towel.
Drizzle an oven tray with olive oil and place in the oven for a few minutes until the oil is piping hot (this helps the potatoes to crisp up). Remove from the oven and gently place the potatoes in the tray. Sprinkle with rosemary and lots of seasoning, mix well and place back in the oven for an hour, turning occasionally.
The potatoes should be soft inside and lovely and crisp on the outside.
