Grapefruit can be impossible to eat by itself without sweetening. But it is a great source of vitamin C and it is an easy tree to grow in the backyard. A slice of this grapefruit yoghurt cake would make a great lunchbox food.

Ingredients
  • 1½ cups flour
  • 2 tsp baking powder
  • ½ tsp salt
  • 1 cup plain yogurt
  • 1 cup (200 grams) plus 1 Tbsp sugar
  • 3 large eggs
  • 1 grapefruit (1 zested and 2-3 juiced )
  • ½ tsp pure vanilla extract
  • ½ cup (120 ml) vegetable oil
  • ⅔ cup granulated sugar (for the syrup)
Instructions
  1. Preheat the oven to 180 C. Grease a loaf tin and then line the bottom with baking paper.
  2. Sift together the flour, baking powder, and salt into 1 bowl.
  3. In another bowl, whisk together the yogurt, 1 cup sugar, the eggs, grapefruit zest, and vanilla. Slowly whisk the dry ingredients into the wet.
  4. With a spatula, fold the vegetable oil into the batter until it is all incorporated. Pour the batter into the prepared pan and bake for about 50 minutes, or until a cake tester placed in the centre of the loaf comes out clean.
  5. Meanwhile, gently heat the 1 cup grapefruit juice and remaining sugar in a small pan until the sugar dissolves and the sugar is dissolved and a little bit syrupy. Set aside.
  6. When the cake is done, allow it to cool in the pan for 10 minutes. While the cake is still warm, pour the grapefruit-sugar mixture over the cake and allow it to soak in. Cool.
