Yogurt and Orange Cake

Method

1. Take an orange. If not organic, scrape the outer peel lightly, then rinse well. Cut into wedges and blend with a mini-pimmer until smooth.
2. Separate the eggs. Whip the 5 egg whites until stiff peaks form.
3. In a bowl, whisk the 5 egg yolks with 170g sugar until the colour lightens.
4. Add 190g butter (softened) and mix gently.
5. Add 125g plain yogurt (full-fat, unsweetened) and mix.
6. Add the blended orange pulp and mix until combined.
7. Sift together 250g flour and 8g baking powder (half a sachet). Add to the mixture and fold gently.
8. Fold the whipped egg whites into the batter using a bottom-to-top motion until just combined.
9. Butter and flour a high-edged cake mould. Pour in the batter and spread evenly.
10. Bake in a preheated oven at 180°C for about 40 minutes, or until a toothpick inserted into the center comes out clean.
11. Let cool, then optionally dust with icing sugar before serving.
