We recommend not using foil to bake potatoes, because as a potato cooks when baked, it naturally releases some moisture within, giving the finished potato a desirable, drier interior flesh. When baked in a foil jacket, this moisture is trapped in the potato, giving the interior a more, ‘gummy’ finish, and while still edible, is not considered the ideal. It’s best to prepare the potato by simply rinsing clean, then piercing the skin with a fork a couple times or so on each side. For more tips on baking fresh, Idaho® potatoes, click HERE
