Blåbärssoppa is a Swedish drink made from blueberries.
Imagine you are outside on a sunny day and you see lots of small, round, dark blue fruits on a bush. Those are blueberries! Blueberries are very good for you, and they taste sweet and a little sour at the same time.
To make blåbärssoppa, people take the blueberries and cook them with water and a little bit of sugar until they become a nice juicy soup. It's like making tea, but instead of using tea leaves, you use blueberries.
Blåbärssoppa is served warm or cold, and it can be drunk like a regular juice or a hot cup of tea. It's very popular in Sweden and some other countries, especially as a refreshing drink during the summertime. It tastes like a sweet and tangy berry flavor that will make you happy!
