orange and almond cake
Deirdre Rooney


4 used orange halves
Butter or oil, for greasing
5 eggs, beaten
200g ground almonds
200g caster sugar
3⁄4 tsp baking powder
100g dark chocolate, melted, to decorate

  1. Put the orange halves in a saucepan, cover with water and bring to the boil. Cover and simmer for 1 hour 15 minutes, checking water levels regularly. Remove and set aside to cool.
  2. Preheat the oven to 180C/160C fan/gas 4 and grease a 20cm round springform cake tin. Roughly chop the cooked oranges and transfer to a food processor or blender. Add the eggs, ground almonds, caster sugar and baking powder, and blitz to combine.
  3. Pour the batter into the prepared tin and smooth the top. Bake for 35-40 minutes, or until a skewer inserted at the centre of the cake comes out clean. Leave to cool completely before removing from the tin, then drizzle with melted chocolate to finish.
