blini \bli"ni\ (bl[=e]"n[=e]; bl[i^]"n[=e]), n. pl.; sing.
   {blin}. [Russian.]
   Russian pancakes of buckwheat flour and yeast, sometimes made
   from white flour; they are usually served folded over, with
   caviar and sour cream on the inside; -- properly, it is a
   plural word (from the Russian plural of blin) but in America,
   often used as singular; thus the common plural {blinis}.

   Syn: bliny, blinis.
