Fiskbullar

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. Fish balls are popular in East and Southeast Asia, Europe , and some coastal countries of West Africa. In Asia 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.: 286  European versions tend to be less processed, sometimes using milk or potatoes for binding. Nordic countries like Norway, Denmark and Sweden each have their own variation.
