  1. Step 1:

    Preheat the oven to 180°C (160°C fan/gas mark 4). Grease and line the base of a 20cm tin with baking paper. Dissolve the bicarbonate of soda in the water and set to one side.

  2. Step 2:

    Cream together the butter and sugar until light and fluffy. Add the eggs and vanilla and beat well until fully combined. Then add the flour and salt to the mixture and fold through until you have an even consistency.

  3. Step 3:

    Roughly chop the whole orange into chunks by hand and then blitz in the food processor, skin (peel) and all. The consistency should be similar to a chunky marmalade. Add this to the cake batter along with the water and bicarbonate of soda, and stir.

  4. Step 4:

    Add the chocolate and stir through to combine. Pour the mixture into your prepared tin and bake in the oven for 45–50 minutes until a skewer comes out clean when inserted.

  5. Step 5:

    Once baked right through, remove from the oven and allow to cool fully on a wire rack. Serve and enjoy.
