Cha Ca Hanoi: The Turmeric Fish with Dill, Its Story and How to Eat It

Chả cá is a Hanoi dish with a street named after it. The fish arrives golden from the grill, and the last part of the cooking happens in front of you: a hot pan, a pile of dill and spring onion, and a loud sizzle. In December 2025 the knowledge of preparing and eating chả cá Lã Vọng was added to Vietnam’s national list of intangible cultural heritage. This guide explains what the dish is, where it came from and how to eat it.

What chả cá is

Chả cá is made from pieces of grilled fish. The traditional choice is cá lăng, a river catfish valued for firm, sweet flesh and few bones. Cooks have tried other river fish, but the sources we read agree that they fall short, either too soft or too bony.

The fish is filleted, cut into pieces and left in a marinade of galangal and turmeric juice, mẻ (a sour fermented rice paste), pepper and fish sauce. The family most closely linked with chả cá keeps its exact recipe a secret, and every kitchen’s version tastes a little different.

How it is cooked

There are two stages:

• Grilling. The marinated pieces are clamped in a bamboo holder or grill rack and turned over charcoal until both sides are golden.
• Finishing at the table. The grilled fish goes into a pan of sizzling fat set over a burner at your table, together with handfuls of dill and spring onion. Some places instead pour boiling fat over the fish and dill in a bowl. Either way, the herbs wilt and the fish is eaten as soon as it is ready.

Professor Đặng Văn Bài, a heritage expert quoted in the press when the dish was listed, described the cooking and eating together as a kind of culinary ritual that joins the skill of the cook with the experience of the diner.

How it began

The dish is tied to the Đoàn family and their house on Hàng Sơn street in Hanoi’s Old Quarter. The Government Portal places its beginnings at the end of the 19th century, and the family and recent press reports usually give the year 1871.

The family tells the story this way: under French rule, their house sheltered patriots connected with the resistance leader Đề Thám, and the hosts served them grilled fish. Regular guests encouraged the family to open a shop, which gave them a living and a meeting place. Vietnamese newspapers repeat this account as family tradition, and we present it the same way.

The shop kept a figure of Lã Vọng (Jiang Ziya, a figure from ancient China), shown sitting and fishing. He is a symbol of a talented person waiting for the right moment. Customers began calling the dish chả cá Lã Vọng after him. Over time the dish became so well known that the street itself, once a paint-selling street, came to be called Chả Cá, or Fried Fish Street.

Why it is national heritage

The Ministry of Culture, Sports and Tourism added “knowledge of preparing and enjoying chả cá Lã Vọng” to the national list of intangible cultural heritage. The decision was announced on the evening of 19 December 2025 at the opening of the Hanoi Culinary Culture Festival in Thống Nhất Park. It became the seventh Hanoi food tradition on the national list, alongside dishes such as Hanoi pho.

The listing names the Đoàn family as the community that created the heritage. Reports differ on how many generations have kept the recipe, but agree that the family still passes it down. The many restaurants that now serve chả cá are credited with spreading it. Heritage experts have also noted a concern: as the dish has spread, many kitchens have moved away from the traditional method.

How to eat it

You make up your own bowl as the fish comes off the pan:

• Put some rice vermicelli (bún) in your bowl.
• Add fish with the wilted dill and spring onion.
• Top with roasted peanuts and fresh herbs such as coriander and Láng basil.
• Spoon over the dipping sauce and eat it while it is hot.

The classic dip is mắm tôm, a fermented shrimp paste, mixed with lime and chilli. Traditional versions sometimes add a drop of cà cuống, an aromatic essence from a water insect, and a little rice liquor. Because the dish is rich, it is often served with spring onion stalks soaked in diluted vinegar to cut through the fat.

Local tip Many restaurants in Hanoi serve chả cá, each in its own style. There is no official list of the best, and we do not rank places we have not reviewed ourselves.

Good to know

• Mắm tôm has a strong smell and taste. If it is not for you, ask the staff what other dipping sauce they can offer.
• The dish combines fish, shrimp paste and peanuts. If you have a food allergy, ask about the ingredients before you order.
• The pan of fat is very hot, so let the staff or your table companions handle it if you are unsure.
