> Anything you put in an oven covered completely in aluminum foil —like a baked potato — is only going to end up baked, not roasted. Actually, this produces a steamed potato. Covering it in foil is a poor technique for this reason. To properly do this: wash the potato, stab the skin a few times with a fork (failure to do this may produce an exploded potato), sprinkle with salt while still damp so the salt adheres, then roast directly on the oven rack (or in a barbecue) until squeezing it gives a fair bit of give.
