1. Prepare the grapefruits: Zest, peel and segment the grapefruits making sure to work on top of a bowl to save all the grapefruit juice.

2. Make the cake batter: Preheat the oven to 180C/160 fan/4 gas mark. Add the yoghurt to a mixing bowl. Use the yoghurt pot as a measuring tool and add the flour, sugar, salt, and oil to the mixing bowl. Then add the eggs, grapefruit juice and zest. Whisk until you have a smooth batter.

3. Bake the grapefruit cake: Grease your cake tin, or use a silicone one and pour in your batter. Place half of the grapefruit segments on the top. Bake for 40-45 minutes, until firmed up, golden and a knife inserted in the center comes out clean. Serve with the rest of the grapefruit segments. Enjoy warm or cool.
