Equipment
Method
Preparation
- Boil whole oranges in a large pot until very soft, then let them cool, halve, remove any seeds, and puree them in a food processor or blender.
- Preheat your oven to 350°F (175°C); grease and line a 9-inch springform pan with parchment paper.
- In a large mixing bowl, beat the eggs and granulated sugar with an electric mixer until the mixture is light and fluffy.
Baking
- Gently fold the orange puree into the egg mixture, followed by the almond flour, baking powder, salt, and the roughly chopped pistachios.
- Pour the prepared batter into your springform pan and bake for 50-60 minutes, or until a skewer inserted into the center comes out clean.
- Allow the cake to cool completely in the pan on a wire rack before carefully inverting and removing it.
Glaze & Garnish
- For an optional glaze, whisk together the powdered sugar with 2-3 tablespoons of fresh orange juice until smooth.
- Drizzle the glaze over the cooled cake and garnish with additional chopped pistachios just before serving.
Notes
Ensure oranges are very tender after boiling to achieve a smooth puree. The cake is best stored at room temperature for up to 3 days, or refrigerated for longer. For a richer flavor, toast the pistachios lightly before adding them to the batter.
