King cakes
The origin of kings’ cake dates from the roman times, and it was not a religious tradition. The cake was served at Saturnalia celebrations (Slaves festivity) in December. It was a commemoration of the renewal of light and the end of the labor in the countryside. At that time the peasants and the slaves had the opportunity to rest and recover from the efforts realized during months. In order to celebrate it, they prepared round cakes, which included figs, dates and honey, and distributed them as a gift for the work well done.
In the III century a dry bean was introduced inside the cakes. It was a symbol of prosperity, and the one that found it would be named “king of kings” during a certain time previously established.
It was in the IV century when the Church converted the festivities in Christian celebrations.
It was in France where they started to celebrate “Le Roi de la Fave” (The king of the bean). Children were the protagonists, and the one that found the bean in the cake was treated with gifts and pampered by everyone on the 6th of January.
Actually in Spain it is a tradition to have kings’ cake (Roscón de Reyes) during the Magic Kings day on the 6th of January, where the Christmas festivities end. Nowadays you can find a bean and a plastic baby or a similar figure. The one that gets the bean has to pay the cake and the one that gets the baby will have good luck.
In South Louisiana it is a tradition to have king cake for Mardi Gras. From the day after Kings Day until Ash Wednesday you can find king cakes in the bakeries, some of them have their own special recipes. These king cakes are decorated with the traditional Mardi Gras colors: purple, green and gold. Inside every king cake a plastic baby is hidden. The tradition is that each person takes a piece of cake, and the one that finds the plastic baby inside is obligated to host the next king cake party and supply the king cake.
It is probable that the New Orleans king cake evolved from the customs of old South Louisiana’s immigrants. In the Picayune cookbook says that New Orleanians started serving king cake as part of the Spanish celebration of King’s Day. However other food historians believe that the New Orleans king cake was really an Italian or a French tradition.
Here you will find an easy recipe of a king cake from Stephanie Gallagher The Iron Chef Mom.
Next, you can also find a recipe of kings’ cake (Roscón de Reyes) that was broadcasted by RTVE as part of the program “La mañana” on December 29, 2011.
I hope you are able to make both cakes and compare them. Happy Mardi Gras!
