How to Assemble

1. Boil the Oranges

Start by washing two whole oranges very well in water. Place them in a pot and cover with water. Boil them for two hours until they are very soft. Drain the water and let the oranges cool down completely.

2. Make the Puree

Cut the soft oranges into quarters and remove any seeds. Place the whole pieces into your food processor now. Pulse until the fruit turns into a very smooth paste. Set this thick orange puree aside in a small bowl.

3. Grind the Pistachios

Clean the processor and add the dry shelled pistachios. Pulse them until they look like a fine green sand. Be careful not to turn them into a greasy nut butter. Mix the ground nuts with the baking powder and salt.

4. Beat the Eggs

Grab a large bowl for the eggs and the sugar. Use your electric mixer to beat them for five minutes. The mix should look pale, thick, and very fluffy. This air helps the flourless cake stay light and soft.

5. Fold the Batter

Add the orange puree and vanilla to the egg mix. Gently fold in the ground pistachios with a large spoon. Stir until the green nuts are fully mixed into the batter. Do not over-mix or you will lose the air.

6. Bake the Cake

Pour the batter into your lined springform baking pan. Bake at 325 degrees for about fifty to sixty minutes. The top should feel firm and look a golden brown. A toothpick should come out clean from the center.

7. Cool and Glaze

Let the cake cool in the pan for ten minutes. Then move it to a rack to cool completely. You can dust the top with powdered sugar for beauty. Serve a slice with a dollop of thick Greek yogurt.
