What is "jacket potato"?

A jacket potato, also known as a baked potato, is a classic side dish that consists of a whole potato that has been baked in the oven until it is tender on the inside and crispy on the outside. The potato is typically prepared by washing and drying it, then pricking it several times with a fork to allow steam to escape during baking. It is then rubbed with oil or butter and seasoned with salt and pepper before being placed in the oven to bake. Once the potato is cooked through, it is often split open and topped with a variety of toppings, such as butter, sour cream, cheese, chili, or bacon. Jacket potatoes are a popular food item in many cultures around the world and are often served as a main dish or side dish with a variety of different entrees.
