pierogi are not vareniki and they are not russian, you russians think everything on earth started in russia:P
What's the difference between your pierogi and vareniki?
I do not have a habit to label things "Russian". :)
you russians think everything on earth started in russia
and wódka is polish.
lol
Well... considering that Mendeleev was partially Polish you're right to a large extent.
and in ukraine every soup is called borsch.
In some areas they probably do but those who I've talked to named that way only beet-soup. So do Russians. Of course taste of all dishes differs depending on particular area. I bet my neughbours' borsch is something different. :)
You're right though saying that Ukrainian food is generally fatty. in Ukraine they threw to borsch the whole piece of salo (pig fat) thus you could only eat it while it was hot. :)
