Rice paper wrappers. Sounds familiar, hmmm, it seems like I had seen a documentary on tv about rice paper wrappers made by a Vietnamese. It is a mix of paste which I did not see the entire procedure. The paste is applied on a wooden plate and heated for a short time then harvested as a thin wrapper. But the lumpia wrapper is a different one from that rice paper wrappers that was made in Vietnam. But anyway, I am going to Vietnam next month so probably I can get more details on this rice paper.
