Want to improve your baked potatoes inside and out? Try brushing the skin with olive oil or melted butter before baking; it'll crisp the skin. And, don't wrap the potatoes in foil, just prick them all over with a fork and bake at 375°F until tender, about an hour.
You can speed up the baking by starting the potatoes in the microwave for 12 minutes, then brush with the oil and butter and finished in the over for 10 minutes.
And, to add even more "oomph", try sprinkling the potatoes with a little coarse sea salt after brushing them with the olive oil or butter.
