Ingredients

  • 2 medium whole oranges
  • 1 cup blanched almonds
  • 1/2 cup shelled pistachios (unsalted)
  • 4 large eggs
  • 1/2 cup honey or maple syrup
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1 tsp vanilla extract (optional)
  • 1 tsp orange zest (optional)
  • 1/4 tsp ground cardamom or cinnamon (optional)

Instructions

  1. Boil the whole oranges in water for about 30 minutes, changing the water once halfway. Let them cool slightly.
  2. Cut the oranges into chunks (remove seeds if any) and blend into a smooth puree, peel and all.
  3. Pulse almonds and pistachios in a food processor until you get a coarse meal—avoid over-processing.
  4. In a large bowl, whisk together orange puree, eggs, honey or maple syrup, baking powder, salt, and any optional flavorings.
  5. Fold in the ground nuts until fully combined without overmixing.
  6. Pour the batter into a greased or lined springform pan.
  7. Bake at 180°C (350°F) for 35–45 minutes or until the edges are set and a toothpick comes out mostly clean.
  8. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before serving.

Notes

  • Try tangerines or lemon zest for a citrus twist.
  • Fold in chopped dried cranberries or apricots for extra texture and sweetness.
  • Add a pinch of cinnamon or cardamom for warm spice.
  • Top with melted dark chocolate or fold in chocolate chips for a richer version.
  • Store at room temperature for up to 3 days or refrigerate for up to 5 days.
