Vobla - dry salted river fish. Or shrimps.
Damn, my Cousin lived at my flat for 3 weeks, and he managed to pour water into a plastic box with vobla in my fridge... Took me 3 days to figure out who died in a fridge, I was seriously looking for a mouse that hanged itself
(Russian expession: "a mouse hanged in a refrigirator" [v holodil'nike mysh povesilas'], means total absence of food).
I don't know any other nation except Russians/Ukrainians/Belorussians who drink beer with vobla. It's a great pleasure to take a fish, knock it against a table and tear it apart
A real beer party
