The "king cake" takes its name from the biblical three kings. In Catholic liturgical tradition, the Solemnity of Epiphany - commemorated on January 6th - celebrates the visit of the Magi to the Christ Child. The Eve of Epiphany (the night of January 5th) is popularly known as Twelfth Night (the Twelve Days of Christmas are counted from Christmas Eve until this night). The season for king cake extends from the end of the Twelve Days of Christmas (Twelfth Night and Epiphany Day), up until Mardi Gras, or "Fat Tuesday;" the day before the start of Lent. Some organizations or groups of friends may have "king cake parties" every week through the Carnival season. In Portugal, whoever gets the King cake trinket is expected to buy the next cake for these get-togethers.
In the southern United States, the tradition was brought to the area by colonists from France and Spain and is associated with Carnival (also known as Mardi Gras). Celebrated across the Gulf Coast region from the Florida Panhandle to East Texas, it originated in French Louisiana and King cake parties in New Orleans are documented back to the eighteenth century.
The king cake of the New Orleans tradition comes in a number of styles. The most simple, said to be the most traditional, is a ring of twisted bread similar to that used in brioche topped with icing or sugar, usually colored purple, green, and gold (the traditional Mardi Gras colors) with food coloring. In 1972, a small bakery in Picayune, Mississippi, Paul's Pastry, started adding fillings to King Cakes filling - the most common being cream cheese, praline, cinnamon, or strawberry. A so-called "Zulu King Cake" has chocolate icing with a coconut filling, because the Krewe of Zulu parade's most celebrated throw is a coconut. Also, some bakers have now taken the liberty to offer king cakes for other holidays that immediately surround Mardi Gras season, such as green and red-icing king cakes for Christmas, red and pink-icing cakes for Valentine's Day, and green and white-icing cakes for St. Patrick's Day. Others have gone a step further and produce specialty king cakes from the beginning of football season for Louisiana State University and New Orleans Saints tailgate parties, then for Halloween, then Thanksgiving - and do not cease until after Mardi Gras season with an Easter holiday king cake. Several markets sell the cakes during the season including Dorignac's. It has become customary in the Southern culture that whoever finds the trinket must provide the next king cake or host the next Mardi Gras party.
The traditional trinket in the cake is a bean, still seen in some European and Mexican traditions but rare in U.S. king cakes. It is echoed, however, in some krewes' use of a gilded bean trinket.
In the U.S. Gulf Coast since the 1950s, the most common trinket has been a small plastic baby doll. Earlier ceramic baby dolls as trinkets are documented in New Orleans back to the 1930s. A king wearing a crown is the next most common trinket. Other figures have been seen historically, and starting in the 1990s again became more common in the more expensive "gourmet" varieties of king cake. In New Orleans in recent years, figurines are sold in the shape of a breast or penis, or depict a man or woman in a lascivious pose. The common plastic baby of today is usually colored pink, brown, white or gold. Because of the potential choking hazard, some bakeries include the trinket separately from the pastry.
The person who gets the trinket is declared the King or Queen of the day. Sometimes there are separate cakes to select the king and queen. In New Orleans, the cake for women is sometimes called a Queen Cake. The king or queen is usually obligated to supply the next king cake or host the next party or both. King cake parties may be held at the homes of people who live on or near the routes of Mardi Gras parades.
In most workplaces, the one who finds the trinket must be bought lunch once a month until the next year, when they must provide the King Cake. The trinket holder also often gets to pick who buys them lunch every month. Another variation on this tradition is simplified so that workers share a king cake at lunch or during the day, with the person receiving the trinket bringing the cake for the next workday.
In Mexico, the one who finds the Baby Jesus must prepare tamales for the Candlemas feast.
King Cake...
2 envelopes active dry yeast
1/2 cup granulated sugar
1-1/2 sticks (6 ounces) unsalted butter, melted
1 cup warm milk (about 110°F)
5 large egg yolks, at room temperature
4 1/2 cups bleached all-purpose flour
2 teaspoons salt
1 teaspoon freshly grated nutmeg
1 teaspoon grated lemon zest
1 teaspoon vegetable oil
1 pound cream cheese, at room temperature
4 cups confectioner's sugar
1 plastic king cake baby or a pecan half
5 tablespoons milk, at room temperature
3 tablespoons fresh lemon juice
Purple-, green-, and gold-tinted sugar sprinkles
Combine the yeast and granulated sugar in the bowl of a stand mixer fitted with a dough hook. Add the melted butter and warm milk. Beat at low speed for 1 minute. With the mixer running, add the egg yolks, then beat for 1 minute at medium-low speed. Add the flour, salt, nutmeg, and lemon zest and beat until everything is incorporated. Increase the speed to high and beat until the dough pulls away from the sides of the bowl, forms a ball, and starts to climb up the dough hook. (If the dough is uncooperative in coming together, add a bit of warm water (110 degrees), a tablespoon at a time, until it does.)
Remove the dough from the bowl. Using your hands, form the dough into a smooth ball. Lightly oil a bowl with the vegetable oil. Place the dough in the bowl and turn it to oil all sides. Cover with plastic wrap and set aside in a warm, draft-free place until doubled in size, about 2 hours.
Meanwhile, make the filling. In a large mixing bowl, combine the cream cheese and 1 cup of the confectioner's sugar. Blend by hand or with an electric mixer on low speed. Set aside.
Line a baking sheet with parchment paper.
Turn the dough out onto a lightly floured work surface. Using your fingers, pat it out into a rectangle about 30 inches long and 6 inches wide.
Spread the filling lengthwise over the bottom half of the dough, then flip the top half of the dough over the filling. Seal the edges, pinching the dough together. Shape the dough into a cylinder and place it on the prepared baking sheet seam side down. Shape the dough into a ring and pinch the ends together so there isn't a seam. Insert the king cake baby or pecan half into the ring from the bottom so that it is completely hidden by the dough.
Cover the ring with plastic wrap or a clean kitchen towel and place in a warm, draft-free place. Let the dough rise until doubled in size, about 45 minutes.
Meanwhile, preheat the oven to 350°F.
Brush the top of the risen cake with 2 tablespoons of the milk. Bake until golden brown, 25 to 30 minutes. Remove from the oven and let cool completely on a wire rack.
Make the icing. Combine the remaining 3 tablespoons milk, the lemon juice, and the remaining 3 cups confectioner's sugar in medium-size mixing bowl. Stir to blend well. With a rubber spatula, spread the icing evenly over the top of the cake. Sprinkle with the sugar crystals, alternating colors around the cake.
