Instructions:

1. Prepare the Oranges:
- Wash the oranges thoroughly to remove any wax or impurities.
- Place the whole oranges in a large pot and cover them with water.
- Bring the water to a boil and then reduce the heat. Simmer the oranges for about 1 hour or until they are very soft. This step helps to remove any bitterness from the orange peel.

2. Cool and Process the Oranges:
- Remove the oranges from the water and let them cool down completely. This can take about 15-20 minutes.
- Once cool, cut the oranges into quarters and remove any seeds.
- Place the oranges (with peel) in a food processor and blend until a smooth puree is formed. Set aside.

3. Prepare the Cake Batter:
- Preheat your oven to 350°F (175°C). Grease and line an 8-inch (20 cm) round cake pan with parchment paper.
- In a large mixing bowl, beat the eggs until they are light and frothy.
- Gently fold in the orange puree into the eggs.
- Add the ground almonds (almond meal) and baking soda to the mixture, stirring until everything is well combined.

4. Bake the Cake:
- Pour the batter into the prepared cake pan, smoothing the top with a spatula.
- Bake in the preheated oven for about 50-60 minutes, or until a skewer inserted into the center comes out clean. The cake should have a golden-brown top.

5. Cool and Serve:
- Allow the cake to cool in the pan for about 10-15 minutes.
- Carefully remove the cake from the pan and transfer it to a wire rack to cool completely.

Your Flourless Orange Cake is now ready to serve.

Tips:

- Make sure to thoroughly boil the oranges until they are very soft; this ensures they blend smoothly and contributes to the moistness of the cake.

- Allow the boiled oranges to cool completely before blending to avoid a bitter taste.

- Use fresh, high-quality almonds for the best flavor and texture. You can also lightly toast the almonds before grinding them to bring out their nuttiness.

- Separate the egg whites and yolks for a fluffier texture. Beat the egg whites until stiff peaks form and fold them into the batter gently.

- Test the cake for doneness by inserting a toothpick into the center. If it comes out clean, the cake is ready.
