Traditionally, cha-gio are wrapped with rice paper. To work with rice paper, you have to wet each sheet so that it is pliable for rolling and folding. I prefer to use wheat wrappers over rice paper because I can exclude that extra step. Also, rice paper doesn't maintain the crispiness as well as wheat wrappers when fried. Cha-gio, wraps with lettuce and assorted Vietnamese herbs (rau thơm) such as fresh mint, cilantro, and Thai basil, or any herbs that are available. Eating these rolls with fresh lettuce and herbs and dipping in nuoc cham sauce helps to reduce the greasiness from deep frying.
