What is a twice-baked potato?

A twice-baked potato is a culinary dish made from a baked potato that has been cut into two equal halves, with its flesh hollowed out and mixed with butter, sour cream, cheese, and other seasonings. The potato is then typically topped with additional cheese and baked again until it is heated through and the cheese is melted. Twice-baked potatoes can be served as a side dish or as a main course. They are often accompanied by additional toppings, such as bacon, chives, or salsa.
