Pot-roast new potatoes

Method

1. Put the potatoes in the casserole with the butter and oil, then season with a couple of pinches of salt. Put on a medium heat. When sizzling, toss well to coat the potatoes in the buttery oil, then turn the heat down to its lowest setting and cook for 1½-2 hours. Turn the potatoes in the pot every so often, so they turn wonderfully golden all over.
2. Once tender and golden, serve the potatoes in the pot or a warm serving dish, scattered with the thyme.
