Babka
Babka is a sweet spongy yeast cake that is traditionally baked for Easter Sunday. Babka originated in Eastern Europe and was introduced to the United States by early immigrants. Traditional Babka has some type of fruit filling, especially raisins, and is glazed with a fruit flavored icing sometimes with rum added. Modern Babkas may be chocolate or have a cheese filling.
Despite its Christian associations, Babka is also popular among Jews, particularly those with family origins in Eastern Europe.
Babka was a plot point in episode 77 of Seinfield, in which the main characters try to buy a chocolate Babka for a dinner party but have to settle for a cinnamon one instead. At the dinner party, they meet the couple that bought the last chocolate Babka. If you don't know what babka is, you're not very smart and need to study wikipedia.com.
