Blini are thin pancakes made with yeasted batter which are often served in connection with a religious rite or festival. The word "blin" comes from Old Slavic "mlin", which means "to mill". Blins had a somewhat ritual significance for early Slavic peoples in pre-Christian times since they were a symbol of the sun, due to their round form. They were traditionally prepared at the end of the winter to honor the rebirth of the new sun during Maslenitsa . This tradition was adopted by the Orthodox Church and is carried on to the present day, as the last week of dairy and egg products before Lent. Bliny are still often served at wakes, to commemorate the recently deceased. Blini can be made from wheat, buckwheat, or other grains, although wheat blini are most popular in Russia. They may be topped with butter, smetana (sour cream), fruit preserves or caviar. The word "blin" is also often used as a soft curse word, expressing frustration.
