I looked that up, and I have not had those yet. I'll have to look for those next time. Leshchina (possibly wrong spelling) is among my favorites at the moment, it's chocolate covered hazelnut goodness. Halva is also delicious!
I tried one for the first time last night and i'm still having PTSD from the texture. I haven't had a lot of the canned goods, but i'm not too fond of what I've had. Salo is pretty good however.
