Kings Cake is a ring-shaped cake, topped with icing and purple, green, and gold sprinkles from Louisiana (and parts of the Gulf Coast). It is eaten during Mardi Season, which runs from Twelfth Night (Epiphany) through Fat Tuesday (the day before Lent). Rosca de Reyes is a ring-shaped, sweet yeast bread (with a cake-like texture) from Mexico. It's decorated with candied fruit to represent a crown's jewels, and is most often eaten on January 6th (Three Kings Day).
