Instructions:

1. Prepare the Oranges:
- Place the whole oranges (with peel) in a pot, cover with water, and bring to a boil.
- Let them simmer for about 2 hours until the oranges are soft. Make sure to check the water level occasionally and add more water if needed to keep the oranges submerged.
- After boiling, drain and let the oranges cool.
2. Preheat Oven and Prepare Pan:
- Preheat your oven to 350°F (175°C).
- Grease and line an 8-inch (20cm) springform cake pan with parchment paper.
3. Blend the Oranges:
- Cut the cooled oranges into quarters, remove any seeds, and blend them to a smooth puree using a food processor or blender.
4. Melt Chocolate and Butter:
- In a heatproof bowl, melt the dark chocolate and butter together. You can do this by setting the bowl over a pot of simmering water (double boiler method) or by microwaving in short bursts, stirring after each interval until smooth.
5. Mix Wet Ingredients:
- In a large mixing bowl, beat the eggs and sugar together until pale and thick, about 3-4 minutes.
6. Combine Ingredients:
- Add the orange puree to the egg and sugar mixture and mix well.
- Pour in the melted chocolate and butter, and mix until fully combined.
7. Fold in Dry Ingredients:
- Gently fold in the ground almonds until the mixture is well combined and smooth.
8. Bake the Cake:
- Pour the batter into the prepared cake pan and smooth the top with a spatula.
- Bake in the preheated oven for 50-60 minutes, or until a skewer inserted into the center of the cake comes out clean or with just a few moist crumbs.
9. Cool and Serve:
- Allow the cake to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
- Serve the cake plain, dusted with powdered sugar, or with a dollop of whipped cream.

Flourless chocolate and orange cake FAQ:

How long should I bake the Flourless Chocolate and Orange Cake?

Bake in the preheated oven for 50-60 minutes. The cake is done when a skewer inserted into the center comes out clean or with just a few moist crumbs.

What size springform pan is needed for this recipe?

You will need an 8-inch (20cm) springform cake pan for this recipe, greased and lined with parchment paper.

Can I use a different type of chocolate for this cake?

Yes, you can use semi-sweet or milk chocolate instead of dark chocolate, but it may alter the cake's flavor and richness.

How should I store the leftover cake?

Store the leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it for up to a week or freeze it for up to 3 months.

What are some substitutions for the almonds in this recipe?

You can substitute ground almonds with ground hazelnuts or a similar nut flour. If you need a nut-free option, consider using a seed flour, such as sunflower seed flour, but note that the flavor will differ.

Tips:

- Prepare the Oranges: Boil the oranges whole until they are soft, about 1-2 hours. This process helps to reduce the bitterness of the peels and brings out a sweeter, more intense orange flavor.

- Use Quality Dark Chocolate: Opt for high-quality dark chocolate with at least 70% cocoa content. This ensures a rich, full-bodied chocolate flavor that complements the oranges.

- Let the Cake Cool Completely: After baking, allow the cake to cool in the pan for at least 20 minutes before transferring it to a wire rack. This helps it set properly and makes it easier to handle.

- Blend Almonds Thoroughly: Make sure to finely grind the almonds to a flour-like consistency in a food processor. This will give the cake a smoother texture.

- Add a Garnish: To add an extra layer of flavor and presentation, sprinkle powdered sugar over the top or garnish with orange zest and shaved dark chocolate before serving.
