Mike said he used to see how his host family made it when he stayed in America. And it was not difficult to make. First, preheat the oven. Then, choose a good potato and wash its skin until it’s clean. After drying the washed potato with a towel, put it into the heated oven and wait for twenty to thirty minutes. When the potato is ready, cut it open and put any food you like on top of it to make it taste even better. 

        After listening to what Mike told her, Vera understood why it is called a jacket potato -- it’s because one eats the potato with its skin on it.
