Aaaa...! Eurica!
I thought you were talking about nutritional yeast, i even don't know why.
What about ordinary yeast,- yes, many people make "drozhzheviye bliny" ("yeast blinis"). I've never like them: they were too fat and dry for my liking, i could hardly digest them, they tasted like dried grass to me. My dad used to make another kind of bliny: very thin, sour, a little wet inside. Those were tasty! But that's my dad. I can say though, that when i was an omni, i tried bliny in the special fast food chain "Tjeremok" (it's very popular, and it makes dishes which, at least, look like traditional russian and ukranian meals). But the food there is super greasy and, in my opinion, even more malicious than in McDuck. Well, "Tjeremok" and other fast food chains now make bliny without yeast, or they put so little quantity into them, that it cannot be felt. My ex bf was a real fan of such kind of blinis with various fillings: most of all he loved rolled bliny with salmon or red caviar inside. I couldn't look at him devouring bliny and burgers every day without tears, but i could do nothing.
P.S. And as far as i know, my granny Nina didn't use yeast either. My sister has been making bliny for this Maslenitsa, - also without yeast,- she was telling me about them and showing photos (they looked pretty normal). The other side of the medal, is that if people don't put yeast,- they, as a rule, add too much eggs. This "recipe" is even more disgusting (IMO).
