Cascarón

They are mostly used in Mexico during Carnival, but in American and Mexican border towns, the cultures combined to make them a popular Easter tradition.

In addition to Easter, cascarones have become popular for occasions including birthdays, New Year's, Halloween, Cinco de Mayo, Dieciséis, Day of the Dead, and weddings.

In order to make cascarones, one can use a pin or knife to break a hole in the end of the eggshell and pour the contents out.

The shell is then cleaned out, decorated as desired, and allowed to dry, before it is filled with confetti or a small toy.

[3] The Los Angeles Star mentioned the eggs in an article about Christmas celebrations on January 4, 1855, saying, "In the city, cascarones commanded a premium, and many were complemented with them as a finishing touch to their headdress."
