Yellow Croaker Fish Balls 黄鱼鱼丸

How it is made

The technique is old and simple: fresh fish is taken apart for its flesh, ground cold, then pounded with salt in a wooden mortar so that the salt-soluble proteins re-form into a network. What comes out is a fine, glossy paste that is spooned into boiling water to set.

A fish ball is essentially fish flesh plus starch, and the shape need not be a sphere — Chinese-language Wikipedia notes kidney shapes and cubes as well. Yellow croaker fits the method because the technique rewards a lean white fish, and the salt is doing the structural work rather than a binder.

What they taste like

Good fish balls are springy with a clean, faintly sweet marine flavour and a surface that resists the tooth. The crisper style is common enough in Taiwan to have its own name, 脆丸, and that is the texture to expect when the paste has been pounded hard and boiled briefly.

Because the paste is mostly fish, the flavour is delicate and takes on whatever broth it is cooked in. That is why fish balls work as a soup ingredient rather than as a dish that carries a sauce.

Where it comes from

Taiwan has a deep bench of fish balls, and Chinese-language Wikipedia names four as representative: 淡水鯊魚丸 from Tamsui, 南方澳鬼頭刀魚丸 from Nanfang ao, 臺南虱目魚丸 from Tainan and 高雄旗魚丸 from Kaohsiung. Each is named for the fish it is made from, which is exactly the naming pattern 黄鱼鱼丸 follows.

The wider family includes 鱈魚丸, 花枝丸 and 蝦丸, so a menu that lists 黄鱼鱼丸 is marking the fish rather than the technique. The article Taiwanese section does not single out yellow croaker, so the fish here is taken from the dish own name.

Ingredients and dietary questions

The ingredients are fish, salt and starch; some makers add egg white or sugar. Starch is part of the definition rather than a filler, although the proportion is what separates a firm ball from a bouncy paste.

Fish balls are seafood, so they are not suitable for anyone avoiding fish, and cross-contact in a kitchen that also handles shellfish is common. Ask about added starch and any egg white if you are eating around an intolerance.

Ordering them

Fish balls appear on menus as 魚丸湯 in soup, on hotpot and oden lists, and as fried snacks. Because Chinese-language Wikipedia notes that Taiwanese fish balls are also packed and sold frozen, they are a supermarket item as much as a street one.

Ask which fish is in the ball if it matters — the difference between the four representative styles is the fish, and a shop that makes its own will usually say so. Portion sizes are small; a bowl is typically six to eight balls.

How they are eaten

In soup they are eaten with a spoon, usually with white pepper or a scatter of chopped spring onion, and the broth is drunk afterwards. Fried, they are eaten hot from paper, and in oden they sit in a soy broth with the rest of the skewers.

The same paste is the base of other Taiwanese fish-paste foods — fish cake, fish noodles and the like — so a kitchen that makes one usually makes several. That shared base is why the fish ball is a good index of how a shop handles its fish generally.
