Ingredients
Orange Curd
Chocolate Sponge Biscuit
Meringue Layer
Mascarpone Custard
Instructions
Step 1
1. Cut the butter into small cubes and place it in the freezer.
2. Pour the orange juice into a saucepan and boil it over medium heat, stirring occasionally, until reduced to 90 ml (3.05 fl oz). Add the lime juice and allow it to cool. A precise reduction will help intensify the flavors.
3. Prepare a double boiler by bringing water to a boil over medium heat. Ensure the water does not touch the bottom of the bowl to avoid cooking the eggs.
4. Mix the egg yolks and brown sugar in a heat-proof bowl and whip them on medium speed for about one minute. Gradually pour in the cooled orange juice.
5. Place the bowl over the double boiler and cook, stirring occasionally, until the curd thickens and coats the back of a spoon, around 20 minutes. Keep an eye on the consistency; it should be thick and creamy.
6. Add the orange zest a couple of minutes before the curd is ready and mix well.
7. Remove from heat and strain through a sieve into a tall glass.
8. Use an immersion blender to blend the curd, adding 2-3 pieces of chilled butter at a time until fully incorporated.
9. Transfer the curd into an airtight jar and store it in the refrigerator.
It's best to prepare the curd a day in advance to allow the flavors to meld.

Variations
Gluten-Free Variation: Simply swap out the regular flour for gluten-free flour in the chocolate sponge and the meringue layers. Make sure your baking powder is gluten-free too. As always, double-check the labels to avoid any hidden gluten. 🥄
Vegan Variation: Replace the egg yolks in the orange curd with a mixture of cornstarch and water (1 tbsp of cornstarch + 3 tbsp water for each egg). Use a plant-based butter and a dairy-free mascarpone for the custard. Additionally, substitute the egg whites in the meringue with aquafaba (liquid from chickpeas), and in the sponge with an egg replacer. 🎂
With these simple swaps, everyone can enjoy a slice of this divine cake, no matter their dietary preferences!
Faq
- Why is my chocolate sponge not fluffy?
Make sure your egg whites are whipped to stiff peaks and gently fold them into the batter. Overmixing can deflate the air you’ve incorporated.
- How do I prevent my meringue from collapsing?
Ensure your mixing bowl is entirely grease-free, and add sugar gradually while whipping to stabilize the foam.
- Can I make components of the cake ahead of time?
Yes, the orange curd and meringue layers can be made a day in advance and stored in the fridge.
- How do I get a smooth mascarpone custard?
Start whipping the cream and mascarpone at a low speed and gradually increase to avoid any lumps.
- What’s the best way to assemble the cake layers evenly?
Use a culinary ring for cutting and assembling, ensuring each layer is level and uniform.
- Can I freeze the cake for later?
It’s best enjoyed fresh, but you can freeze individual slices wrapped in cling film and foil. Thaw in the fridge before serving.
