Delicious soft and sweet yeasted bread filled with a wild blueberry sauce and quark. Quark is a German style soft cheese, said to be similar to ricotta cheese, cottage cheese, or even farmer cheese. This fresh cheese is a fresh acid-set cheese, which sours the milk and gives it a tangy flavor. When combined with sweet, fresh blueberries it creates a perfect pairing! You don’t have to forage for wild blueberries to make these delicious Russian-inspired buns, but you can certainly romanticize yourself wandering through an enchanted wood as you enjoy each delicious bite!
