Roast potatoes (outdoor barbecue) 

butter, cream, or cooking oil is applied to the surface of potatoes and then wrapped in a thick piece of aluminum foil. Cover with the lid of the oven and bake over medium heat for about an hour and a half, turning occasionally to evenly heat all parts. Before serving, you can open an "X" shaped opening in the part of the potato. 

According to the taste of each person, salt, pepper, butter, cheese, onion, and other seasonings can be added to make the potato taste different.
