Hot blueberry soup is the signature refreshment of Vasaloppet, the 90-kilometre ski race run in Dalarna since 1922, and skiers drink it by the cup at stations along the course.
Blåbärssoppa is a warm, lightly sweetened soup-drink made by simmering dried or fresh wild blueberries and thickening them slightly with potato starch, traditionally sipped from a cup to warm up and refuel during cold winter activities. It has a tart-sweet flavor and a thin, syrupy texture.
