Double Cook

After potato choice, the key to these potatoes is the fact that they’re doubled-cooked. So many roasted potato recipes have you put raw potatoes in the oven, which is easy, but doing that won’t give you a potato with two distinctive textures. If you parboil your potatoes first, they get a head start so the oven doesn’t have to penetrate into the middles. Parboiling makes sure the insides are cooked and creamy. Since the potatoes go in the oven hot, the oven heat can concentrate on crisping up the outsides. Plus, when you parboil in salted water, you’re seasoning the insides of the potatoes.
