I have this assignment due.. Do you know what festival cocadas (coconut candy) come from and any information about it? I have searched the web but can not find anything only recipes that I have already got. I have asked my teacher, family members and friends weather they know anything about the festival and what role the food plays in the festival. They don't anything and i need help.
