Gỏi cuốn,[1] Vietnamese spring roll, fresh spring roll, spring roll, or rice paper roll,[2][3][4][5][6] is a Vietnamese dish traditionally consisting of pork, prawn, vegetables, bún (rice vermicelli), and other ingredients wrapped in Vietnamese bánh tráng (commonly known as rice paper or cold roll).[7][8] Like other spring roll dishes, they are believed to have an origin in China and were introduced to Vietnam by Chinese immigrants although the gỏi cuốn has been modified to suit local tastes.[9][10]Gỏi cuốn are served fresh while others are served fried, like the Vietnamese chả giò.[11] They are served at room temperature (or cooled) and are not deep-fried or cooked on the outside. These rolls are considered to be a very popular appetizer with customers in Vietnamese restaurants.
