Savor a bowl of cao lau for breaksfast. You can order it from vendors or any noodle restaurant on Thai Phien Street or Hoi An Market. Cao Lau is a regional Vietnamese dish made with noodles, pork, and greens, and is only found in the town of Hoi An. It is likely that the origin of Cao Lau in Hoi An dates back to the town’s history as a trading port. Prior to the Chinese establishment in Hoi An, in the 17th century, the town was also a centre of Japanese trading activity. The famous Hoi An Bridge also dates to this period.
Cao Lau noodles are clearly derived from Japanese soba noodles. Although there are some who claim that they are Chinese wheat noodles, they are not made of wheat and have a different texture. There are as many variations on this dish as there are households in Hoi An. The noodles are Cao Lau; the way the pork is cooked (or omitted), the greens (the use or absence of mint), the use of lime or chili jam, these are all variations on a theme.
