Orange Ring Cake - cooking recipe

Ingredients

2 None large oranges
3 cups chopped hazelnuts
1 3/4 cups sugar
1 tsp vanilla extract
1 tbsp baking powder
9 None eggs
5 oz dark chocolate, broken into pieces

Preparation

Place the whole, unpeeled oranges in a saucepan, cover with water, put on a lid and bring to a boil. Simmer over a low heat for 2 hours. Drain and allow to cool.
Preheat the oven to 325\u00b0F. Grease a ring mold pan. Cut the oranges in half and remove the seeds. Place the oranges in a bowl and puree with a hand blender.
In a separate bowl, mix the hazelnuts, sugar, vanilla extract, baking powder and a pinch of salt. In a third bowl, beat the eggs until creamy with a hand mixer. Stir in the orange puree, then the hazelnut mixture in 2 batches. Spoon into the pan and smooth out. Bake for 1 hour, or until a skewer comes out clean, covering with aluminum foil 20 mins before the end of the baking time.
Allow to cool in the pan for 40 mins, then turn out on to a wire rack and allow to cool completely.
Melt the chocolate in a heatproof bowl set over a pan of simmering water. Allow to cool a little, then drizzle over the cake so it runs down the sides. Allow to dry.
