What is "blueberry soup"?

Blueberry soup is a traditional Scandinavian dish that is typically served as a dessert or a snack. The soup is made from fresh or frozen blueberries, which are cooked with sugar and water to create a sweet and tangy base. The soup may also include other ingredients such as cinnamon, vanilla, lemon juice, or cornstarch to thicken it. Blueberry soup is often served chilled and garnished with a dollop of whipped cream or a sprinkle of chopped nuts. It is a popular dish in Sweden, Finland, and Norway, and it is enjoyed both as a refreshing summer treat and as a comforting winter dessert.
