Sicily is huge in traditions and values certain Holidays over others. On Christmas Eve it is tradition to celebrate the feast of the 7 fishes like in the Bible and one is required to eat seven different seafood dishes that night.
Also a huge tradition is to Easter a day in which many families stay up making easter bread. A cross between a cookie and bread that is not to be eaten until the day of, for one should not be indulging in such food prior to that day, again this goes along with the religion of Sicily.
Above is a picture of my mother's Easter bread from this years Easter 2011.
Another tradition that is less formal that the above to is just the action of kissing one another when saying hello or goodbye on both cheeks of one's face, if you fail to do so it is considered disrespectful to the recipient.
