Potatoes can be baked in the oven or cooked in the microwave. The microwave version has a soft skin. For a crisper skin, baking in the oven is optimal. Rubbing on a little olive oil, salt and freshly ground pepper (lots of pepper for me) before cooking is a way to infuse more flavor into the potato during cooking and get a crispier skin. Or, just toss the cleaned, dried and pierced potato in the oven with nothing else.
