Vietnamese Sour Spring Roll, Nem chua is a meat roll with a sweet, sour, salty and spicy taste. Nem chua possesses the local character of each region of Vietnam, due to the differing ingredients and sauces used.

These contents are mixed thoroughly before being wrapped with aromatic, fresh leaves into small, boxy rolls before being stored for the fermentation process for three to five days in a cool place before eating.
