Hoi An’s Famous Cao Lau Noodles
The History, Ingredients, Preparation, and Where to Find This Signature Dish
The historic trading town of Hoi An in Central Vietnam is a popular stop for tourists on the Saigon-Hanoi trail. Dutch, Chinese, Japanese, and Indian traders came to Hoi An to conduct business and exchange goods until the 17th century. While waiting for their ships to be unloaded, the traders would rest on the second floor of a riverfront restaurant with a view and enjoy a steaming bowl of cao lau noodles.
Trading and shipping have long since moved north to Da Nang, however, cao lau is still a source of pride for locals in Hoi An. The unique noodle dish can only be made in Hoi An.
Cao Lau Noodles
Perhaps the differentiator between cao lau and other noodle dishes is the texture. Cao lau noodles are firmer and chewier – very similar to Japanese udon – than those found in typical Vietnamese noodle dishes such as pho. Unlike pho, cao lau noodles are served with very little broth. The broth is seasoned with cilantro, basil, and mint; sometimes chili peppers and a lime are provided on the side. Cao lau should be served with salad greens and bean sprouts, although many restaurants leave these important ingredients out to save cost. Unless ordered vegetarian, thinly-sliced pork slices and deep-fried croûtons are sprinkled on top to complete the dish.
Why can’t cao lau be made anywhere else in Vietnam? The secret lies in the water; authentic cao lau is prepared only with water drawn from ancient Cham wellshidden around Hoi An and Quang Nam Province. Noodles are pre-soaked in well water and lye made from wood ash brought from one of the eight Cham Islands around 10 miles outside of Hoi An. The combination may seem esoteric, but local foodies can tell a difference in the taste and texture!
Finding Authentic Cao Lao in Hoi An
Cao lau literally appears on every menu around Hoi An – both in the Old Town and on streets outside. With every eatery in town advertising some interpretation of the dish, finding authentic cao lao can actually be daunting. Many restaurants leave out key ingredients or do not use well water; some places are cheeky enough to use pho broth thinking that tourists will not know the difference!
If you do not mind the hassle and hectic environment, authentic cao lau can be purchased from stalls in the outdoor market on the east end of Bach Dang Street along the river. Otherwise, try your luck by approaching one of the handful of restaurants that also operate a cooking school; many schools have students prepare authentic cao lau as part of the course.
Eating Cao Lau
Despite the preparation time, cao lau is usually cheap to eat – under $2 a bowl. Although cao lau is served in most restaurants until close, locals prefer to eat the dish either for breakfast or lunch, giving plenty of time to digest the firm noodles.
Other Hoi An Specialties
White Rose: Cao lau isn’t the only local dish to try while in Hoi An. White rose – an appetizer named for its shape when presented properly – is a plate of delicate noodle dumplings. Ingredients such as shrimp and pork are placed on top the carefully folded noodles rather than inside as in other dumplings.
Hoi An pancakes: Nothing like the “pancakes” we know in the West, Hoi An pancakes are widely available on menus around Hoi An. Sometimes listed as “country-style pancakes”, this filling appetizer is quite an interesting project. You will receive an egg omelet stuffed with veggies, a bowl of water, a plate of salad greens and mint leaves, and several sheets of hard rice paper resembling plastic!
To eat Hoi An pancakes, dip the rice paper quickly through the water which makes them sticky and pliable. A delicate juggling act of rolling the omelet and greens while holding the sticky paper should yield a delicious pancake similar to an extra-thick spring roll. Hopefully one of the staff will provide some friendly guidance to get you started!
