Wash the untreated orange, rub dry and rub the peel. Then peel all oranges so that the white skin is completely removed. Cut out fillets between the parting skins and dab dry. Squeeze the parting skins and collect the juice. Beat fat and sugar with the whisk of the hand mixer until foamy.
Stir in eggs one after the other. Mix flour, starch, baking powder, salt and orange peel and stir in. Also stir in 2 tablespoons of orange juice. Carefully fold in the fillets. Pour the dough into a greased and breadcrumbed box form (25 cm long). Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 60-65 minutes. Let it cool down a little, turn out of the tin and let it cool down completely. Mix icing sugar and about 3 tablespoons of orange juice. Spread on the cake and let it dry.
