Cao lau hoi an also known as Hoi An vermicelli refers to a special food found in the Center of Vietnam. Cao lau noodles are carefully made from local new rice not old and stocked one. Water used to soak rice must be taken from Wells in the Ba Le Village; noodles thus will be soft, enduring and flavored with special sweet-smelling. In addition, meat used to prepare for Cao lau must be loin or trotter.

On the other hand, the dry pancakes used must be thick and have much sesame. Greasy coconut quintessence and bitter green cabbage are also indispensable. The so-called genuine Cao lau Hoi An must satisfy all above requirements.
