What is "potato skin"?

A potato skin is a popular appetizer that consists of the crispy outer layer of a baked potato that has been topped with a variety of ingredients, such as cheese, bacon, sour cream, and chives. The potato skin is typically prepared by baking a whole potato until it is cooked through, then cutting it in half and scooping out the flesh, leaving behind a thin layer of potato skin. The skins are then brushed with oil or butter and baked until crispy and golden brown. Once they are removed from the oven, they are topped with a variety of ingredients and served hot as an appetizer or snack. Potato skins are a popular food item at sports bars and casual dining restaurants and can be customized with a variety of different toppings to suit different tastes and preferences.
