Perfect Flourless Orange Cake

Place the oranges in a large saucepan and add enough water to cover. Bring to a boil and boil for 2 hours over medium heat. Check occasionally to make sure they do not boil dry. Allow the oranges to cool then cut them open and remove the seeds. Process in a blender or food processor to a coarse pulp.

Preheat the oven to 375 degrees F (190 degrees C). Thoroughly grease a 10-inch round cake pan and line it with parchment paper.

In a large bowl beat the eggs and sugar together using an electric mixer until thick and pale about 10 minutes. Mix in baking powder and saffron (optional). Stir in the pureed oranges. Gently fold in almond meal and candied orange peel (optional); pour batter into the prepared pan.

Bake until a small knife inserted into the center comes out clean about 1 hour. Allow the cake to cool in the pan. Tap out onto a serving plate when cool.
