Fish balls are the balls made from fish paste which are then boiled or deep-fried. Similar in composition to fishcake, fish balls are often made from fish mince or surimi, salt, and a culinary binder such as tapioca flour, corn, or potato starch.[1][2]
Fish balls are popular in East and Southeast Asia as well as in Nordic countries,[3] where they are eaten as a snack or added to soups or hotpot dishes. They are usually attributed to Chinese cuisine and the fish ball industry is largely operated by people of Chinese descent.[4]: 286 European versions tend to be less processed, sometimes using milk or potatoes for binding. Nordic countries like Norway, Denmark and Sweden also have their own variation.
Production
There are two variants of fish balls, differing in textures, production method, and primary regions of production.
Asia
While the ingredients and methods are similar between countries, differences can be noted in terms of elasticity, colour, and flavour. Fish balls in Hong Kong and the Philippines can be more firm, darker, and have more fishy taste and aroma than their Malay and Singaporean counterparts.[5] Taiwanese fish balls have more bounce and more air incorporated to allow for soaking up soups or sauces.[6]
Typically fish are shredded, coarsely ground, or pounded, then undergo prolonged mixing with added salt and crushed ice until a smooth texture is attained. Other ingredients are added, such as sugar, monosodium glutamate, transglutaminase, or starches, and then water is added to ensure the ball has a "soft, springy texture." This technique, similar to the process of making surimi, uncoils and stretches previously wound and tangled protein strands in the fish, which produces food with a firm "bouncy" texture. In Taiwan, the term "Q" is used to describe this ideal bouncy texture.[7]
In commercial production, the balls are shaped by an extruding machine, and set in water between 30 and 45 C. before boiling, cooling, then packaging.[4]: 287, 291 The setting time is an important part of manufacture because in addition to giving the balls a translucent appearance, the shape will be maintained after packaging. They can be sold uncooked (after setting), boiled, or fried (after being boiled).[4]: 291–293
The variety of fish used in surimi can affect commercial fish ball production, due to the difference in thermal stability between tropical fish and cold-water fish.[4]: 290 Economically, fish ball production adds value to lower-priced fish.[8]
Europe
Scandinavian fish balls are made of completely pureed fish, milk, and potato flour (or potato starch), and they are shaped without additional processing, which produces a softer texture. This type of fish ball usually comes in metal cans or transparent plastic containers containing stock or brine and also requires a setting period prior to canning.[9]
Shelf life
Fish balls are perishable, and have a different shelf life based on the amount of processing and the inclusion of additives. Uncooked fish balls have a shelf life of 4 to 5 days when stored at 5 °C.[10] A fried, marinated fish ball can last up to 135 days at ±4 °C.[11]
Mislabeling issues
While fish balls can contain other seafood or meat products (such as squid, cuttlefish, or shrimp balls), studies conducted on processed seafood have revealed significant amounts of mislabeling. A 2017 study in Italy and Spain detected mollusks used in surimi products, which is a concern for shellfish allergies.[12] A 2013–2016 study in the Philippines that identified the genetic code of a variety of fish balls concluded that large, well-established companies generally adhered to labelling standards, but unknown, small producers typically supplying street hawkers revealed seafood balls that contained pig or chicken meat.[13] A 2019 study by the National University of Singapore showed a 7.8% mislabeling rate for single-type seafood products, and 38.5% mislabeling for products containing multiple meat sources. The study also identified seafood balls containing pig DNA, although none of the samples were labeled as a halal or kosher food, which would pose a significant concern for the country's Muslim population.[14]
Regional variations
Greater China
Mainland China
Fish balls have a long history in China, and the introduction of fish balls throughout Asia is often attributed to Chinese immigrants. Fish balls can also contain a wide array of seafood and other meats such as beef or pork.[4]: 288
In Hubei, fish balls are made from freshwater fish surimi. A Fuzhou variety (福州鱼丸) is made from fish with a minced pork filling.[15][4]: 289 The variation from Fuqing is much larger. Shark is also used; about 50% of shark caught in China is used for fish ball production with a small amount used for export.[16]
Tengxin Foods (Fujian) is one of China's largest fish ball factories, with a 30% market share.[4]: 289
Hong Kong and Macau
Fish balls are one of Hong Kong's most popular and representative "street foods",[17] eaten plain or cooked in a curry sauce.[18][19] Readily available in traditional markets and supermarkets, fish balls are also a popular ingredient in hot pot.
Flathead mullet (九棍魚/烏仔魚) and daggertooth pike conger (門鱔) are common fish varieties used for fish balls. Originally they were likely made by mixing and frying the remaining materials of Chaozhou fish ball (潮州白魚丸) or stale fish, although more recently they are mainly imported by wholesalers and the texture is more consistent.[20]

There are three kinds of fish balls, known as 魚蛋 (literally "fish eggs"), sold in Hong Kong and Macau. They are yellow, white, and golden. Yellow fish balls are most commonly sold as street food. White fish balls are larger in size and made with white fish, such as Spanish mackerel, with an elastic (bouncy) and fluffy texture and a strong taste of fish. This kind is usually served to complement noodles at Cháozhōu-stylenoodle restaurants,[21] and at some cha chaan tengs, which also sell beef balls (牛丸) and cuttlefish balls (墨魚丸). White fish balls from traditional fish ball restaurants are made from fresh fish and are normally hand-made (手打) by the owners using traditional techniques. Golden fish ball is a snack in Cheung Chau. Distinguishing features include size, sauce and texture. They can be fist-sized and are served with a special curry sauce, and they are mainly made from fresh fish which makes the texture smoother.
During the 1970s and 1980s, "fish ball girl" became a euphemism for underage female sex workers.[22][23] The 2016 Mong Kok civil unrest, which escalated from the government's crackdown on unlicensed street hawkers during the Chinese New Year holidays, has been referred to by some media outlets and social media platforms as the "Fishball Revolution" (魚蛋革命).[19]
Taiwan
Milkfish balls (虱目魚丸) are frequently found in Taiwan. The natural texture and aroma of the milkfish give this variant a unique taste. This is one of the main ways milkfishes' lesser-prized yet highly abundant white meat is consumed. Other fishes used include shark, lizard fish, pike eel, and marlin.[4]: 298
Fish balls with roe (魚包蛋) are served at hot pot restaurants. They have a sweet and salty taste with a popping element from the roe's texture. There is also a fried golden version.
Southeast Asia
Singapore

In Singapore, fish balls are also known as known as 鱼圆 (yú yuán) or 魚丸 (yú wán).
Traditionally, fish balls were made from locally sourced fish such as coral fish and dorab. Production scale varies from individual hawker stalls to large corporate factories which supply the local and export markets. Due to higher labour costs and limited local fish supplies, surimi are mostly imported, and fish balls are produced at a lower cost by mixing surimi with fresh leached fish mince. Higher quality fish balls are made from wolf herring, coral fish, Spanish mackerel, and conger eel.[4]: 286–287
As of 2002, Singapore consumes approximately 10 kg of fish balls per capita per year, possibly the country with the highest consumption of fish balls in the world.[4]: 286–287 They can be served with soup and noodles like the Chiuchow style or with yong tau foo (酿豆腐). They can also be served with noodles called mee pok.
Bak chor mee, a popular Singaporean dish which comes in both dry and soup versions, was listed as the top world street food by World Street Food Congress.[24] In some cases, it is also fried and served on a stick. Fish balls are the second most processed fish-based product in Singapore, roughly 10% of the total produced.[4]: 287

Indonesia
In Indonesia, fish balls are called bakso ikan (fish bakso) and often served with tofu, vegetables, and fish otak-otak in clear broth soup as tahu kok. It may be thinly sliced as additional ingredient in mie goreng, kwetiau goreng, nasi goreng and cap cai. A similar dish is called pempek, in which surimi is shaped into logs and fried. There are some dishes of fish ball soup called bakso kakap (snapper fish ball soup) from Semarang[25] and bakso ikan marlin (sailfish or blue marlin fish ball soup) from Pesisir Barat, Lampung.[26]
Brunei
In Brunei, fish balls are called bebola ikan.
Malaysia
In Malaysia, fish balls are known as 鱼丸 (yú wán in Mandarin Chinese, jyu4 jyun2 in Cantonese, or hî-oân / hîr-oân / hû-oân in Hokkien) or 鱼蛋 (yú dàn in Mandarin, jyu4 daan3 in Cantonese), and bebola ikan in Malay. Popular dishes include fish ball noodle soup.[27]
Philippines
In the Philippines, there are fish balls (pishbol) and a similar dish called bola-bola, which is the same meat paste as fish cake, but wrapped in a wonton skin.[28]Yellowtail fusilier, corn starch and baking powder are common ingredients.[4]: 288
Thailand
In Thailand, fish balls are fried or grilled as snacks.[29] In main dishes, fish balls are in Chinese style noodle soups and curry dishes such as Kaeng khiao wan luk chin pla, a green curry.[4]: 289
Known as Fiskbullar in Sweden and fiskeboller in Norway and Denmark, Nordic fish balls are white and without breading.
In Norway, fish balls (fiskeboller[30]) are made using wheat and potato flour, milk, fish broth, salt and seasonings. When canned, they are packed in fish broth. Haddock is commonly used.[9] They are commonly served with potatoes, carrots and/or cauliflower or broccoli in a white sauce. The sauce is often made with the stock from the container, sometimes with mild Madras curry seasoning as a condiment, or mixed to create curry sauce. Adding ketchup to the sauce is commonplace among children. Tiny fish balls called suppeboller (literally "soup balls") are also common in fish soup. Sideboller is made from coal-fish.[30]
In Sweden, fiskbullar are normally served with mashed potatoes or rice, boiled green peas and dill, caviar or seafood sauces.
In Iceland has two varieties; Fiskbollur[ˈfɪskˌpɔllʏr̥] is very similar to those of Norway and Sweden,[31] whereas Fiskibollur[ˈfɪscɪˌpɔllʏr̥] are fried brown in a pan.[32] Both varieties are served with boiled potatoes, carrots, lettuce, and either bechamel or Madras curry sauce.
In the Faroe Islands, fish balls are called knettir and are made with groundfish and mutton fat.
Germany
German fish balls, known locally as fischklößchen, rely heavily on herbs and herb sauces.
Gefilte fish, typical of Ashkenazi Jewish cuisine, has origins in 14th century non-Jewish Germanic cookery. Originally a stuffed fish dish, it suited the dietary cultural needs for Jewish celebrations, being an acceptable form of meat as well as already deboned which adheres to the restriction on picking through bones on the Sabbath. Jewish communities have their own versions based on local ingredients, such as the addition of sugar in Poland, black pepper in Lithuania, and cooking it in a tomato sauce in Libya.[33]
England
A classic English variant (as well as in the US) uses cooked mashed potato and egg as a binder, and is pan fried. Cod is a popular fish for this style.[34] "The Lone Fish-ball" was published in 1855 by George Martin Lane referencing this type of fish ball popular in New England.[35]
Italy
Italian fish balls, known locally as polpette di pesce, are fried with Parmesan cheese and breadcrumbs, and usually served with a tomato sauce. They can be found both as rounded balls and as patties.
