Step-by-Step Instructions
1. Prepare the Mango Confiture Center
In a small saucepan, combine the mango purée, sugar, and lime juice. Bring to a gentle boil over low-to-medium heat, stirring occasionally to prevent scorching.
Once heated through, blend the mixture with an immersion blender or whisk until smooth. Strain through a fine mesh sieve to remove any fibers for the cleanest texture.
Pour the strained purée into 1–1.5-inch silicone half-sphere molds. Freeze until completely solid, 6–8 hours or overnight.
Pro Tip: Fully frozen inserts are essential for sharp layers and easy assembly later.
2. Make the Hazelnut Praline Crunch
Place the sugar in a small saucepan and bring to a boil over medium-low heat. Once boiling, reduce the heat and allow the sugar to cook undisturbed until it turns a deep amber color.
Remove from heat and immediately stir in the chopped hazelnuts until evenly coated. Spread the mixture into a thin layer on a silicone mat or parchment paper and allow it to cool completely.
Once hardened, break into small chunks and set aside.
Pro Tip: This praline provides crucial texture contrast against the soft mousse and fruit center.
3. Prepare the Crème Fraîche Mango Mousse
Bloom the gelatin in cold water for 5–10 minutes.
In a saucepan, combine the mango purée and sugar. Bring to a gentle boil, stirring until the sugar dissolves completely. Remove from heat and stir in the bloomed gelatin until fully melted and smooth. Set aside to cool to room temperature.
In a stand mixer fitted with the whisk attachment (or using a hand mixer), whip the cold heavy cream to soft peaks.
Once the mango mixture has cooled, gently fold in the crème fraîche, followed by the whipped cream, using a spatula to maintain an airy texture. Transfer the mousse into a piping bag.
4. Assemble the Mango Mousse Halves
Pipe the mango mousse into the mango mold cavities, filling them about halfway.
Insert the frozen mango confiture half-spheres into the center. On one side of each half, press a small amount of hazelnut praline crunch into the mousse.
Top with additional mousse to fully enclose the inserts, smoothing the surface.
Freeze the filled molds for 6–8 hours or overnight, until completely solid.
5. Form the Full Mango Shapes
Once frozen solid, carefully demold the mango halves. Pair two halves together to form a full mango shape, gently pressing to adhere.
Return the assembled mangoes to the freezer until ready to coat.
Chocolate Velvet Finish
6. Prepare the Chocolate Velvet Coating
Melt the white chocolate and combine with coconut oil until smooth. Add mango oil-based flavoring if using.
Divide the chocolate mixture into separate bowls:
300 g for yellow
25 g each for orange, green, and red accents
Color each portion with oil-based food coloring gels.
7. Coat and Color the Mangoes
Insert two toothpicks into each frozen mango mousse to help with dipping.
Dip each mango into the yellow chocolate coating, gently shaking off excess. Place onto a parchment-lined tray and freeze for 10–15 minutes to set.
Using a sponge (whole or cut into pieces), lightly dab orange chocolate along one side of the mango, followed by green on the opposite side. Finish with subtle touches of red to mimic natural ripeness.
Return the mangoes to the refrigerator or freezer for 5–10 minutes to fully set.
Serving and Storage
Allow the mango illusion cakes to thaw in the refrigerator for 2–3 hours before serving. This ensures the mousse becomes soft and creamy while maintaining structure.
Storage Tips:
Refrigerator: Up to 48 hours, covered
Freezer (before coating): Up to 1 month
Frequently Asked Questions
Q: Can I use canned mango purée?
Yes, as long as it’s unsweetened and high quality. Adjust sugar as needed.
Q: Why use crème fraîche instead of cream cheese?
Crème fraîche adds gentle tang without heaviness, keeping the mousse light and refreshing.
Q: Do I need oil-based food coloring?
Yes. Water-based coloring will seize the chocolate coating.
Q: Can I spray instead of dipping?
Yes, chocolate velvet spray works beautifully if you prefer an airbrushed finish.
