In Germany, a bun with herring is a delicacy. More and more often you can also find it in Polish towns on the Baltic Sea as a local treat. We do not have to only eat fish for dinner, as they are equally good in the form of pastes on sandwiches. A popular one is Polish paprikash, which tastes delicious, when cooked well and made of good fish. It was inspired by the African street food, which was learned and tasted by Polish technologists who sailed around Africa on ships.
Fish can be also found in a surprising form, e.g. in the form of fish crisps or a more obvious patty form, sometimes used for burgers. Another common product is a small portion of the so-called small herring ("śledzik" in Polish), thanks to which we can supplement our diet with fish more often, but in smaller portions. It is worth using it in such a form.
