Black Sea mussels run noticeably smaller and sweeter than their Atlantic cousins, thanks to the sea's unusually low salinity.
Black Sea mussels are steamed open in a garlicky white wine broth and served in the pot with bread for dipping, a staple of Varna's harborside grills and seafood stalls.
Why it's made this way: The Black Sea's low salt content shapes a distinct local shellfish, and Varna's fishing fleet built a whole harborfront eating culture around it.
