When people think of Hoi An, they often picture its moss-covered ancient streets and colorful lanterns. But they also remember Cao Lau, a signature dish deeply rooted in the culture and history of this heritage town. Unlike pho or other Vietnamese noodle dishes, Cao Lau has a distinctive flavor, featuring chewy golden noodles, tender char siu pork, fresh herbs, and a rich dressing.

For many travelers, enjoying a bowl of Cao Lau in the heart of Hoi An Ancient Town is an essential part of the Hoi An experience.

The origin of Cao Lau

Cao Lau is believed to have appeared around the 17th century, when Hoi An was a bustling international trading port where Vietnamese, Japanese, and Chinese merchants interacted. This cultural exchange contributed to the creation of a unique dish that combines culinary influences while retaining its own local identity.

The name “Cao Lau” is traditionally thought to be associated with the fact that merchants in the past often sat on upper floors of restaurants, allowing them to enjoy their meals while observing the busy trading activities below.

What makes Cao Lau so special?

1. Cao Lau noodles

The most distinctive element of Cao Lau is its noodles.

Cao Lau noodles are pale yellow, slightly wider than pho noodles, and chewy without being overly firm. Traditionally, rice is soaked in alkaline ash water made from locally sourced wood before being ground into flour and steamed several times to achieve the characteristic texture.

This elaborate preparation gives Cao Lau noodles their unique texture, which is difficult to replicate elsewhere.

2. Flavorful char siu pork

Pork is marinated with a combination of spices such as five-spice powder, soy sauce, garlic, onions, and honey, then braised or roasted until tender and infused with flavor.

The meat has an attractive reddish-brown color and a well-balanced sweet and savory taste.

3. Fresh Tra Que herbs

A delicious bowl of Cao Lau is incomplete without fresh herbs and vegetables.

These are often sourced from Tra Que Vegetable Village, a famous agricultural area near Hoi An. Common ingredients include lettuce, basil, aromatic herbs, young mustard greens, and bean sprouts.

The fresh local vegetables add a refreshing balance to the rich flavors of the noodles and pork.

4. Just the right amount of dressing

Unlike pho or other noodle soups, Cao Lau is not served with a large amount of broth.

Only a small amount of flavorful dressing is added to coat the noodles. This allows diners to fully appreciate the chewy noodles, savory pork, and fresh herbs.

5. Crispy pork crackling and fried rice crackers

A bowl of Cao Lau is often topped with crispy pork crackling and pieces of fried rice crackers, creating an appealing combination of soft, chewy, and crunchy textures.

The secret lies in several factors :

• • Traditional noodle-making techniques

Together, these elements create the distinctive character that makes Cao Lau an iconic specialty of Hoi An.
