Martha Stewart shared her method for achieving the best baked potato in a new video on The Kitchn. The secret is to bake the potato in a preheated oven at 400°F for about an hour, then let it rest for 10 minutes before slicing it open. She also recommends using a fork to prick the potato all over before baking, and rubbing it with butter and salt as soon as it comes out of the oven.
