Maybe it was the luck of the Irish, but yesterday's festivities got me thinking about fortuitous foods. Whenever anyone in my family travels, my mother prepares a large pot of Ping An Mien, the Chinese chicken noodle soup pictured above, for safe travels. Before my friend Jaime ran her first marathon, she had to eat a certain dish at her favorite Italian restaurant for good luck, and many Southerners will tell you they can't start a new year on the right foot without black-eyed peas. Tell me, what are your lucky foods?
