About Cao lầu
Cao lầu, in its typical form, is found exclusively in Hội An. The rice noodles are soaked in alkaline water, which gives them their firm, chewy texture and yellowish color; according to legend, the water comes from the city's ancient Bá Lễ well. It is served with pork, herbs, sprouts, crispy dough pieces, and just a splash of broth.
