ORANGE UPSIDE-DOWN CAKE

Steps:

• 1. Preheat the oven to 350°F.
• 2. Wash the orange. Cut off and discard the ends. Cut the orange crosswise into slices about 1/4 inch thick. Remove any seeds. Put in the skillet, add 1/4 cup water,and sprinkle with sugar. Bring the mixture to a boil over high heat, gently stirring to keep the fruit from sticking. Cook until the liquid is almost gone and the orange slices are caramelized. With a fork, move the orange slices into an attractive pattern in the bottom of the skillet.
• 3. In a small saucepan, heat the milk until warm but not hot. Remove from heat and add 1 teaspoon of the sugar and the yeast. Stir until the yeast is dissolved.
• Set aside.
• 4. In a large bowl, beat together the 2 egg yolks, the remaining sugar, and the margarine until pale yellow and thick. Add the orange zest and vanilla; mix well. Sift the cornmeal into the egg mixture, stirring constantly. Stir in the yeast mixture,which should now be frothy.
• 5. In a clean bowl, beat all 4 egg whites until they form stiff peaks. Stir a third of the beaten whites into the cornmeal mixture. Carefully fold in the remaining whites. Spoon the batter in dollops over the orange slices in the skillet. Smooth the top.
• 6. Bake for 25 to 30 minutes, until a cake tester inserted in the middle comes out clean. Run a knife between the sides of the skillet and the cake. Cool on a rack for 10 minutes. Hold a flat serving plate over the skillet and invert the cake. Serve while still warm.
