Tamsui Fish Ball Soup | New Taipei Signature Dish

For many people, a bowl of fish ball soup is the first hot food they reach for after stepping off the ferry at Tamsui. The fish paste is hand-beaten from sailfish, giving the balls a thin skin and a springy bite, with a filling of minced pork or shrimp; the broth is clear but not thin, simmered on fish bones. Overshadowed by the fame of agei, fish ball soup is actually the older of the two — the everyday soup dish with deeper roots on the old street.

What is Tamsui Fish Ball Soup?

Fish balls are made from sailfish paste (historically also shark paste), mixed with salt and tapioca starch and beaten repeatedly until the mixture becomes elastic, then shaped into rounds and stuffed with minced pork or shrimp filling before being blanched in boiling water to set. The skin is springy without being tough; when you bite through it, the filling releases its savory juices. The broth is typically a light stock of fish bones or pork bones, seasoned with nothing more than salt and white pepper — deliberately kept mild to let the natural sweetness of the fish balls speak for itself, with no heavy sauces added.

Tamsui sits at a river mouth with historically abundant seafood. Large fish such as sailfish and sharks were processed into fish paste as a way of making full use of the catch. During the Japanese colonial period, old street vendors were already supplying dock workers and fishermen with fish ball soup, which gradually became a morning staple for local residents. In the era when ferry culture was at its height, commuters traveling between Tamsui and Taipei by boat would often stop for a bowl of hot soup before boarding — cementing the place of fish ball soup in the food history of the old street.

How to eat it like a local

🥢

Bite first, then drink the brothGently bite into the fish ball and let the meat juices spread in your mouth before sipping the broth. Don't rush to swallow it whole — this is the way to taste the contrast between the fish skin and the filling.

🧄

Go easy on the condimentsStalls usually set out soy paste and chili sauce. Try the broth plain first to gauge how flavorful the fish balls are on their own, then add condiments sparingly — you don't want to mask the fish paste flavor.

🕗

Go early for the freshest batchLong-standing stalls typically start selling in the early morning. Afternoon fish balls are from a prepared batch; morning ones are freshly cooked and have the best texture. Aim to arrive before 10 a.m.

🍡

Pair with agei for a complete mealIt's local practice on Tamsui Old Street to have agei and fish ball soup together as a meal — the savory, fragrant tofu complements the clean, light soup, and the two are understood by locals as the natural pairing.

Visitor tips

The old street is crowded on weekends and individual stalls may sell out early. A weekday morning visit is recommended, or come outside the afternoon peak.
Fish ball preparation varies between stalls; some use commercially produced fish paste. You can ask whether the balls are house-made before buying — self-made stalls typically charge a little more.
Most seating is outdoors or under arcades. On rainy days, bring your own umbrella or choose a shop with indoor seating.
