Blåbärssoppa

Blåbärssoppa is a Nordic fruit soup made from bilberries, which can be served cold or hot. It is sweet and contains starch, which gives it a fairly thick consistency. It is served either as soup, often together with porridge, or as a drink.
In the United States, Swedish blåbärssoppa is imported and sold under the trade name Blåbär. Blueberry soup can be home-made from bilberries, sugar, water and potato starch, or it can be bought ready-made or in powdered form to mix with water.
The Swedish word for bilberry, blåbär, literally means 'blueberry', but the beverage is not made from the North American blueberry, but from the related but distinct European blueberry, Vaccinium myrtillus, which grows in the wild throughout Scandinavia and other parts of Europe.

Uses

Blueberry soup is traditionally served to the participants at the ski marathon Vasaloppet, as it is rich in energy. Bilberries have traditionally been used to combat mild gastrointestinal ailments, and in Sweden and Finland, blueberry soup is often considered suitable food for people with an upset stomach, also because it is energy-rich.
