Baked potato

A baked potato, known in some parts of the United Kingdom as a jacket potato, is a preparation of potato originating from South America, specifically Peru. It may be served with fillings, toppings or condiments such as butter, cheese, sour cream, gravy, baked beans, and tuna, among others. Some varieties of potato, such as Russet and King Edward, are more suitable for baking than others, owing to their size and consistency. Despite the popular misconception that potatoes are fattening, baked potatoes can be part of a healthy diet.
