A fishcake (sometimes written as fish cake) is a food item similar to a croquette, consisting of filleted fish or other seafood with potato patty, sometimes coated in breadcrumbs or batter, and fried.
Fishcakes as defined in the Oxford Dictionary of Food and Nutrition are chopped or minced fish mixed with potato, egg and flour with seasonings of onions, peppers and sometimes herbs.
The fishcake has been seen as a way of using up leftovers that might otherwise be thrown away. In Mrs Beeton's 19th century publication Book of Household Management, her recipe for fishcakes calls for "leftover fish" and "cold potatoes." More modern recipes have added to the dish, suggesting ingredients such as smoked salmon and vegetables.
Fish cakes can be made by the combination of fish paste and surimi. The fish paste is usually a combination of salt, water, flour and egg. The combined product is then shaped and left to cool.They are then battered and breaded using a machine.Then, they are usually fried with oil at around 180 °C and should reach the internal temperature of 74 °C. After the cooking process, they are frozen and packaged and are kept frozen until used.
According to Chinese folk tales, fish cakes have had more than 4000 years’ history. In ancient times, an emperor called Shun travelled to Southern China with his two wives. After a long period of travel, his wives were tired and had bad appetites. This caused Shun to worry, and he searched for ways to resolve the problem. A fisher called Bo came and gave Shun his fish cakes. Shun’s wives really enjoyed them, and their appetites returned to normal. Shun was so pleased that he asked the fisher Bo to teach other people how to make fish cakes, so everyone can enjoy food even when they have bad appetites. Fish cakes then became popular in China.
Later in the history, a famous version of fish cake occurred during Guangxu Emperor’s reign in the Qing Dynasty (1875-1908). Guangxu Emperor’s wife, Zheng loved fish cakes. She brought the fish cakes’ recipe into the forbidden city, where royal family lived. With Royal cooks’ improvement to the recipe during practise, Zheng’s fish cakes eventually became famous. However, the fish cakes also disappeared after Zheng was murdered.
Japanese fishcakes were introduced to Korea during the Japanese forced occupation (1910–1945), and the first eomuk processing plant in Korea was DongKwangFood in Bupyeong Kkangtong Market during 1950s in Busan.
In 1953, Park Jae-Deok who learned eomuk processing from Japan founded Samjin Fish Cake which has the longest history in Korea. It was shortly after the outbreak of Korean War and many refugees migrated to Busan, resulting in booming eomuk industry.
In early 1990s, Busan-eomuk commonly sold in food trucks became a trend. The term Busan-eomuk started referring to long, sausage shaped eomuk. Since the food trucks usually served eomuk with a hot broth, eomuk became one of the most popular fast food in winter season. Even in contemporary Korea, eomuk food truck can be easily spotted on major downtown streets.
In 2010s, eomuk industry in Korea goes through a major transformation from the public perception of eomuk as a fast food to a recognized delicacy. In 2013 December, Samjin Fish Cake established an eomuk bakery, for the first time in Korea. A store that sell variety kind of eomuk in a bakery style. A store that sell variety kind of eomuk in a bakery style.
Up to this day, Samjin Fish Cake solidified unique conception and image of eomuk. Other eomuk processors attempted to transform their stores and diversified their menu to secure lucrative position and remain competitiveness.
Commonly, fishcakes used cod as a filling; however, as cod stocks have been depleted, other varieties of white fish are now used, such as haddock or whiting. Fishcakes may also use oily fish such as salmon for a markedly different flavour.
Fishcakes have also traditionally been made from salted fish (most commonly cod, haddock, or pollock). Fishcakes are also prepared without breadcrumbs or batter, and are made with a mixture of cooked fish, potatoes, and occasionally eggs formed into patties and then fried.
As fish has traditionally been a major dietary component of people living near seas, rivers, and lakes, many regional variations of the fish cake have arisen.
Variations can depend on what type of fish is used; how finely chopped the fish is; the use of milk or water; the use of flour or boiled potatoes; the use of eggs, egg whites, or no eggs; the cooking method (boiling, frying, or baking); and the inclusion of other ingredients (for example, shrimp, bacon, herbs, or spices).
In Newfoundland and Labrador, the fish is generally salted cod flakes and is blended with mashed potatoes. Savory is used instead of parsley, along with minced sweated onions. The cakes are then formed into rounds and cooked in oil or pork back fat until golden brown.
In Barbados, fishcakes are made from salted codfish and flour batter, then fried in oil.
In Denmark, fiskefrikadeller are slightly elongated, pan-fried patties much like regular frikadeller. They are normally not breaded. A similar dish which is boiled, rather than fried, is called fiskeboller and added to certain soups, though it may be closer to a fish version of a knödel. In Southern Jutland, fiskefrikadeller sometimes contain smoked pork fat.
In West Bengal, several local fish species (mostly riverine) are prepared and eaten in deep-fried breadcrumb covered fishcakes, locally called maacher chop. The item is very popular as an appetizer during middle-class Bengali festivities.
Indonesian varieties of fishcakes are locally known in South Sumatra as pempek or empek-empek. The traditional South Sumatran pempek is served with kuah cuka. These fishcakes are usually round or tube-shaped.
Fishcakes in Japan are commonly made from surimi, a paste made primarily from freshwater fish meat and starch, egg whites and spices. After formation, they are commonly fried or boiled before packing and distribution. Based on the Japanese Food Regulations, Fish Cakes made from Fish Paste should be sterilized for 45 minutes at 80℃, measured in the centre. After sterilization, the fish paste should also be stored below 10℃ with frozen fish pastes requiring a minimum storage temperature below -15℃.
In South Korea, fishcakes are called eomuk (어묵) or odeng (오뎅, which is a loan word from the Japanese stew, oden). Fish cakes are mainly made of corvina or cuttlefish which contains less fat. This is because fatty fish are not suitable for making fishcakes. Salt, sugar, flour, and starch are necessary ingredients as well. Also, other ingredients may be added in order to make fishcakes: onions, carrots, green onions, and cooking wine. It is normal to add several chemicals in order to have a better flavor such as D-sorbitol (an artificial sweetener which has approximately 60% of the sweetness of sugar so that diabetic patients can consume), soy protein (protein extracted from soy which can make it possible to create a better texture of fish cakes with less amount of fish fillets), and D-xylose (a natural sweetener with low calories), or monosodium glutamate (MSG).
Usually made by deep-frying paste made from ground fish, eomuk can be boiled with other ingredients to make eomuk-tang (어묵탕; "fishcake soup") or eomuk-jeongol (어묵전골; "fishcake hot pot"), stir-fried to make eomuk-bokkeum (어묵볶음), and put in various dishes such as jjigae and gimbap.
Sold from street carts, eomuk can be boiled on a skewer in broth. The broth is sometimes provided to the customer in paper cups for dipping and drinking. Hot bar, also written as hotbar, is another version of eomuk sold during cold weather. While still served on a stick or skewer, the hot bar is deep-fried instead of boiled. In this form, the hot bar can be prepared according to any particular vendor's 'secret' recipe: plain, mixed with vegetables such as diced carrot or whole perilla leaf, or served with any number of sauces or condiments including ketchup and mustard.
In Norway, "fiskekaker" are made much like the Danish fiskefrikadeller. They are fried and served with potatoes or pasta, broccoli and raw grated carrot, and often brown sauce instead of white.
The type of fish used vary with availability and recepie: Pollock, haddock, herring, wolf-fish and even salmon or trout are sold, and they are often marketed named after the fish they are made of; Seikaker, Koljekaker, Steinbitkaker, etc. Terms like "burger" is also used; "Lakseburger, "Fiskeburger".
Additionally there is fishballs and fishpudding, both more often served with white sauce.
Fishcakes and Fish balls should be prepared from one or more kinds of fish. They may contain starch, additional condiments or government permitted colouring agents. Fishcakes must contain at least 40% of fish under governmental regulations.
Homemade fishballs and fish cakes can also be made using store bought or homemade fish paste. Fish paste that are sold commercially have to contain more than one fish, with possible additions of condiments, colouring agents or starch. Based on the Singaporean government Food Regulations, Fish Pastes should contain at least 70% fish. Homemade fish cakes are usually made mackerel because of its sweeter taste and ease in preparing. Fish paste mixtures are often put in the food processor or traditionally thrown against the side of the mixing bowl to achieve the bouncier texture of the fish cakes. They are then shaped by hand or in molds into various shapes and sizes and stored in the refrigerator or freezer till use.
In Sweden, canned fiskbullar are widely found; in contrast to fiskefrikadeller, they are not fried but boiled and as a result are almost entirely white.
In Thai cuisine, the fish is first mashed and then mixed with chopped yardlong beans, fresh cilantro (including stalks), fish sauce, kaffir lime leaves, red curry paste, and an egg binding. This is deep fried and usually served with a sweet chilli dipping sauce. Thot man pla have become popular around the world.

In Yorkshire, England, the “Yorkshire fishcake” is a variation traditionally served in many fish and chip shops in South Yorkshire, parts of West Yorkshire, and Humberside. It consists of two slices of potato (sometimes parboiled), with offcuts of fish in between, deep fried in batter. Yorkshire fishcakes can also be known as scallop fishcakes, or fish patties. TV chef Brian Turner has made the recipe available via his website. Another variation of the fishcake is the parsley cake which is sold in some fish and chip shops in and around Castleford, West Yorkshire, England. It consists of minced fish, mashed potato and fresh parsley, coated in breadcrumbs and deep fried.
In Saint Helena, fishcakes are made from locally caught tuna or wahoo scraped into mashed potato with herbs and spices, then moulded into cakes and fried in oil. They are often spicy or, as locals would describe, "with bite".
In Vietnam, fishcakes are made of fresh fish, sometimes along with flour. The fishcakes can either be fried or steamed/boiled.
In the Philippines fishcake is eaten as street food and as a component, topping on dishes like noodle soup. Fish Balls are eaten as street food, usually on a skewer or in a cup, paired with a dipping sauce and are usually ball shaped or cylinder shaped. Kikiam is another variety where it is almost prepared like an eggroll. A mix of fish and/or shrimp and ground pork is wrapped in bean curd skin (tawpe), before steaming and then frying.
The nutrients in fish cakes are mainly contributed by freshwater fish, the main ingredient in fish cakes. Asian-style fish cakes are usually high in protein, calcium, and low in fat. For example, per 100g of Japanese fish cakes (kamaboko) has approximately 113.6 Calories, in which 12.3g are carbohydrates (4%) (including dietary fiber of 0.12g), 13.2g protein (26%), 0.67g fat (1%) (composed of 0.092g saturated fat, 0.33g polyunsaturated fat and 0.078g monounsaturated fat), 48.0 mg cholesterol (16%), 845.5 mg sodium (35%), and 241.1 mg potassium (7%).
As for western fish cakes or fish patties, there is no significant difference in the nutritional aspects with their Asian counterparts. However, the western fish cakes are relatively in higher fat content. Western fish cakes or patties have approximately 201 Calories per 100g, contributed by 12.38g carbohydrate (4%) (including 1.1g dietary fiber and 1.03g sugar), 13.65g protein, 10.49g fat (16%*) (including saturated fat 2.245g, polyunsaturated fat 3.085g and monounsaturated fat 4.418g), 55 mg cholesterol (22%), 279 mg sodium (14%), and 463 mg potassium. The percentage daily values above are based on a 2000 Calories diet so may vary depending on the caloric needs of the consumer.
Fish cakes are cooked in different manners based on the cuisine.
In North America, it is common practice to pan fry the fish cakes and are often served as appetizers  whereas in Asia it is often served boiled in soups or as an accompaniment to noodles. Some common dishes in Asian countries that include fish cakes are Udon, Fish Cake Soup, Fish ball Noodles or just served individually as a side dish.
When it comes to manufacturing fishcakes, according to Singaporean fishcake production, fish meats are first defrosted and then ground. After the grinding process, fish meats and all ingredients needed are blended together at high speed. Normally, salt, sugar, flour, and starch are necessarily added to mashed fish fillets. It is good to add salt which approximately weighs 3% of the fish fillets’ weight. Also, other ingredients such as vegetables (onions, carrots, or green onions) or chemicals such as MSG can be added for a better flavor only if the ingredients are suitable for the local requirement. Next, the fish paste is formed so that it can be baked or deep-fried. In order to properly preserve fishcake product, during the process of baking or frying, eradication of enzymes and microorganisms is necessary using heat. For instance, Canada has a specific regulation that the fish cakes should be heated to 65 °C for one minute to destroy the salmonella that may be present. After fishcakes are finally filtered, it is sent for packing and it is now ready to deliver.
Fishcakes are also often sold in fish markets in individual pieces. To keep the fish cakes fresh they are often sold in bags full of water. (Picture 3) These fish cakes are not fried and usually used in soups.
The label must include the product name, the allergen information and the price of the product.
If carton is used in packaging it is usually are made up of solid white cardboard,paper or chipboard.The material used is then coated with wax, plastic or aluminium foil. The manufacturers then have the option to freeze, defrost or vacuum package it. (Picture 2)
When carton is used to the package fish cakes, it is coated with polyethene. This is so that any strain on the inner layer will not result in damage to the outer layer.
The packaging is reliant on whether the fish cakes are pre-wrapped or not. It may be made up of pure white board or duplex board. Carbon Dioxide controlled atmospheres are prime conditions for fish cake storage.
