6 eggs, separated
1 cup sugar
300g (3 cups) ground almonds(almond meal)
1 tsp baking powder
Wash oranges and boiled them (unpeeled) in a pot (it is water in the pan) for 2 hours.
Drain the water and allow the oranges to cool.
Blend the oranges in a blender or food processor to a smooth consistency.
Preheat oven to 180° C – 356° F.
Beat the egg yolk and sugar using an electric mixer until smooth. Add the orange puree and beat. Add the baking powder and ground almond and beat at low speed until just combined.
Beat the egg whites in another bowl until firm peak forms. Add the whites to the almond batter and fold in gently until just combined.
Grease a spring form baking pan with margarine (or vegetable oil spray).
