Banh cuon is made of rice flour. Rice, which is thoroughly selected, is soaked for a night, then ground with a stone mortar.
Viscous flour is spread on the screen, then a lid covers the screen.
We wait until the flour is done to a turn. We use a bamboo stick to strip the thin layer of flour off the screen, then roll it up and sprinkle it with fried onion. The dressing comprises lean meat, deshelled shrimp, thin-top mushroom, dried fungus, onion, fish sauce, pepper. The mixture is stir-fried.
