Simple oven-baked potato

Preheat the oven to 190°C. Scrub the potato, dry it and prick it in several places with a fork. If using oil, brush the skin lightly and season with salt.

Put on a baking tray and bake for about 1 hour, until a knife goes easily into the center. Continue if still firm.

Use oven gloves to remove it. Split carefully and serve with optional butter or sour cream.
