Equipment

  • 1 cake tin 12x9 inches / 30x23cm in diameter and 2-3 inches / 5-7.5 cm deep
  • Blender

Ingredients

  • 1 orange with skin without seeds
  • 1 pink grapefruit
  • 3 eggs
  • 2.3 fl. oz/70 ml olive oil
  • 6 oz/170 g sugar
  • 9 oz/250 g self-raising flour

Note: If you don’t have self-raising flour you can easily make it by using plain flour and baking powder to a ratio of 50 grams of plain flour to 1 teaspoon of baking powder.

Instructions
 

  • Preheat oven to 350°F/180°C
  • Add the oil, sugar, and eggs to a blender.
  • Wash your orange and grapefruit under running water and pat dry.
  • Chop up the orange into slices with the skin still on and remove any seeds. Add the seedless slices to the blender.
  • Cut the grapefruit in half. Remove the skin from one half and discard. Add the skinless half and the half with skin into the blender.
  • Blend ingredients until smooth (around 5 minutes)
  • Next sieve the self-raising flour into a large bowl.
  • Slowly add the liquid mixture from the blender to the flour and continue to stir until the mixture and flour are combined.
  • Cover a cake tin with some baking paper and pour the mixture into the tin.
  • Bake at 350°F/180°C for around 40 minutes (slightly less time for a fan-forced oven).
