This is a recipe from Cook’s Illustrated. Like all recipes from Cook’s Illustrated, the scientific research leads to an unexpected answer. The answer, in this case, is “start the potatoes covered and in a cold oven.” Allowing the potatoes to heat-up along with the oven enables them to be perfectly creamy all the way through without the outside getting either dry or overcooked. The kids will (usually) eat these like candy – please don’t tell them that they’re actually good for you!
