King cake is the food to celebrate Mardi Gras: a ring of dough, cinnamon-streaked, filled or plain, liberally topped with sugar in purple, green and gold, the traditional colors of Carnival. Die-hard Louisiana expats often have it shipped, but sometimes find it at a local bakery. As a proud member of the New Orleans diaspora, I'm always delighted when manifestations of Crescent City culture appear in unanticipated corners, says Mark Plotkin, president of Amazon Conservation Team in Arlington, Va., a rainforest-saving nonprofit.
