Yeah, it took me a while to get used to the jam in tea thing, but since they kept serving it to me, I eventually got used to it. As far as blini goes, they love that. I remember once, we were dining with someone who spoke no English and my Russian was limited. The blini came with something that looked for all the world like Eagle Brand milk. I tasted it, and yep.....Eagle Brand milk-ish. Yet, I knew it was homemade and indeed not Eagle Brand milk. I knew enough to ask in Russian if the stuff was made of milk and sugar and he informed me it was. So I told DH it was pretty much Eagle Brand milk and at that point, he decided to eat it. (DH often lets me be the "taster" as I am a more adventurous eater.) DH applied a thin layer of the stuff and the Russian said, "Nyet, nyet, nyet!" and then the Russian plopped a big old dollop of the Eagle Brand milk-ish stuff on it. "Da!" DH said to me that he could feel his arteries clogging, but he ate it up.

It was yummy.
Russian desserts are usually nothing to write home about, but the apple cake is good. Actually, I love Russian food, but much of it isn't the sort you could easily make and take for a class project. Oh, the pelmini and perogies! (But their perogies aren't like the Polish ones....those are more like pelmini.) Oh, the scrumptious soups. DH did get stunned once when he ordered petite sturgeon at a restaurant and when they brought it out it was 2-3 feet long, all curled around a platter. He thought "petite" meant it would be little, but then I asked him if he had any idea how large an ADULT sturgeon was.......because the thing on his plate WAS petite. But it's not as if you're going to be hauling sturgeon to class.

If you had a Russian store by you, I'd say go in and buy miniature chocolate bars. DD did that and the kids loved them. They usually have gorgeous wrappers.
Anyway, for ease, the apple cake is good. I think apple is "yablaka" in Russian.
