When Dominick Lee was in elementary school in the 1990s, every year for Twelfth Night, the teacher would bring a king cake for the class to share. He and his classmates would wait for their slices -- decorated with purple, gold and green sugars -- eager to see which piece had a tiny plastic baby hidden inside. Whoever found it was responsible for bringing another king cake to school the next week, and the cycle would continue through Carnival season, right up until Mardi Gras.
