Jacket potato rescipe is a simple, comforting dish made by baking whole potatoes until the skins are crisp and the inside is soft and fluffy. Large potatoes are washed, pricked, rubbed with olive oil, and sprinkled with salt before baking. Once cooked, the potato is split open and the flesh is fluffed with a fork. It can be topped with butter, cheese, sour cream, baked beans, or vegetables for a filling meal.
