Hanna, are you sure I think the berries on your second pic are actually blueberries? They look like bilberries to me, although, of course, both species look alike. When I was a kid, I lived in a place where there were lots of both брусника and bilberries in the nearby forests . I liked bilberries, never could get enough of them, because they are hard to pick in large quantities. Same story with the tiny and delicious forest strawberries. Used to take a lot of time to fill a glass jar. Garden strawberries just don't taste the same, too bland, too watery. Even the sweetest varieties can't compare with the wild ones. As to lingonberries aka cowberries, we made pies with them (with a lot of sugar), or squashed them with a lot of water to produce a bitter-sourish cold drink that was quite refreshing.
