Rumor has it that Marco Polo brought the cascarón to Europe from China, where locals use a specially filled egg in a festival manner. The cascarón (meaning "eggshell") has since evolved and become prominent in celebratory customs and holidays in Mexican and Latin-American culture. In San Antonio, cascarones are synonymous with Easter and Fiesta. It's then when they're sold by the dozen at grocery and seasonal specialty stores, roadside stands and by Fiesta vendors. Workplace floors littered with broken eggshells, tissue paper and confetti are commonplace in April. "It's a fun, easy tradition," said Kristelle Aly, administrative assistant at The Fiesta Store, which sells cascarones with every other thing one would need to adequately celebrate Fiesta. "You dye the egg, make a little hole, drain it, put in confetti or whatever and cover the hole. But I've been bad about it: Some family members and I have put flour in the egg."
