Among countless local delicacies, Cao Lau holds a special place, standing as an indispensable symbol of Hoi An’s culinary culture. More than just a dish, Cao Lau is a story of history, cultural exchange, and the passion for food passed down through generations.

1. The Origin and Journey of Cao Lau

Cao Lau appeared in Hoi An hundreds of years ago, during the period when the town was a prosperous trading port with lively exchanges between Vietnam, Japan, China, and Western countries. This dish is a vivid testament to cultural interaction bearing similarities to Chinese cuisine and Japanese noodle-making techniques, yet preserving a unique Vietnamese identity.

The name “Cao Lau” itself sounds elegant and traditional. It is believed to originate from the old term referring to the “upper floors” of ancient eateries, where merchants once sat to enjoy their meals, discuss business, and overlook the bustling streets below.

Thanks to its strategic location on the Maritime Silk Road during the 17th–18th centuries, Hoi An became a cultural crossroads. This convergence gave rise to a diverse culinary heritage, with Cao Lau as one of its finest representatives. While its noodles may resemble Japanese udon or Chinese noodles, the preparation and flavor are entirely distinctive showcasing the creativity and refinement of local people.

Cao Lau is not a coincidence but the result of thoughtful adaptation to local tastes and ingredients. It is not merely food, but a living part of Hoi An’s history, carrying centuries of prosperity and cultural exchange.

2. The Unique and Elaborate Preparation of Cao Lau

What makes Cao Lau truly special lies in its meticulous and elaborate preparation, from ingredient selection to execution skills passed down through generations. Each step is an art form in itself.

Cao Lau Noodles – The Soul of the Dish

The noodles are the most important element, defining the identity of Cao Lau. Unlike pho or vermicelli, Cao Lau noodles are made from local rice soaked in ash water derived from trees on Cham Island. This ash water gives the noodles their light yellow hue and signature chewy, crispy texture.

Even more uniquely, the dough must be kneaded using water from Ba Le Well, an ancient well in Hoi An believed to contain ideal minerals that give the noodles their perfect elasticity and purity of flavor. The dough is then rested, rolled, hand-cut, steamed, and sun-dried to achieve the ideal firmness and sheen.

The “Sacred” Broth

Unlike noodle soups, Cao Lau uses very little broth just enough to coat the noodles. The sauce is simmered from pork bones and char siu drippings, resulting in a thick, amber-colored sauce with a rich yet balanced sweetness. Long simmering and careful seasoning create a glossy, aromatic base that ties all ingredients together.

Char Siu Pork – A Chinese Touch

Pork belly is marinated with five-spice powder, garlic, fish sauce, sugar, and a touch of honey, then slowly braised or grilled until tender inside with a caramelized exterior. Thinly sliced, the pork adds depth, sweetness, and aroma to the dish.

Fresh Herbs – A Taste of the Countryside

Cao Lau is served with a variety of fresh herbs such as mustard greens, basil, fish mint, and bean sprouts. Most notably, these herbs come from Tra Que Vegetable Village, known for organic farming and distinctive flavors. The freshness of the herbs balances the richness of the noodles and pork.

Crispy Noodles and Fried Pork Rind

Crispy fried noodle bits and crunchy pork rind are added for texture and richness. These elements enhance both flavor and mouthfeel, making each bite more exciting.
