Ingredients
- Mango puree
- Fresh lemon juice
- Granulated sugar
- Eggs
- Egg yolks
- Unsalted butter
- All-purpose flour
- Baking powder
- Fine sea salt
- Sour cream
- Safflower oil
- Vanilla paste
- Water
- Fresh lime juice
- Egg whites
- White chocolate
Instructions
- Whisk and cook curd. In a saucepan, combine mango puree, lemon juice, sugar, eggs, and yolks, cooking over medium heat until thickened before whisking in butter.
- Cool and strain. Strain the curd through a fine-mesh sieve into a bowl set in an ice bath, stirring until cool before refrigerating for four hours.
- Prepare the sponge. Preheat oven to 325°F, grease a nine-inch round pan, and whisk together flour, baking powder, and salt in a bowl.
- Whip and combine. Whip eggs and sugar until thick, fold in a mixture of sour cream, oil, and vanilla, then gently incorporate the sifted dry ingredients.
- Bake the cake. Pour the batter into the prepared pan and bake for 75 to 80 minutes until a toothpick comes out clean.
- Simmer the syrup. Combine water, lime juice, and sugar in a small saucepan, heating until the sugar dissolves, then set aside to cool completely.
- Prepare the meringue. Whisk egg whites, sugar, and water over a double boiler until 140°F, then beat in a stand mixer until a stiff, glossy meringue forms.
- Complete the buttercream. Beat softened butter into the cooled meringue, then add vanilla paste and melted white chocolate until the frosting is smooth and satiny.
- Assemble the layers. Level the cooled cake, slice into four layers, brush each with lime syrup, and stack with layers of buttercream and mango curd filling.
Notes
- Ensure all ingredients are at room temperature before starting the meringue to prevent the butter from curdling.
- Always strain your mango puree through a fine-mesh sieve to achieve a perfectly smooth and luxurious curd texture.
- Use a serrated knife and keep the cake chilled to ensure clean, professional-looking horizontal layers.
- Store the cake in the refrigerator but bring it to room temperature for twenty minutes before serving to soften the buttercream.
