Start by blooming the gelatin in cold water for about 5 minutes until it softens. Meanwhile, blend blueberries with sugar until smooth and strain to get blueberry puree. Heat the puree gently, then add the bloomed gelatin and stir until fully dissolved. Pour the mixture into a shallow dish and refrigerate for 2-3 hours until set, creating a beautiful jelly layer for your Lemon Blueberry Domes.

In a mixing bowl, blend cottage cheese, heavy cream, fresh lemon juice, and sugar until velvety smooth. Ensure no lumps remain for a creamy texture. In a separate bowl, whip heavy cream until stiff peaks form; be sure to chill your beaters for the best result. Gently fold the whipped cream into the lemon mixture until fully combined, creating a light, airy mousse that will complement the jelly in your domes.

Preheat your oven to 350°F (175°C). In a mixing bowl, combine all-purpose flour, sugar, and other sponge ingredients, mixing until just combined. Pour the batter into a greased baking pan and smooth the top. Bake for 20-25 minutes, or until the sponge is golden and springs back when touched. Allow it to cool completely on a wire rack before cutting it into rounds that will fit atop the mousse layers.

Once the blueberry jelly is set, it’s time to assemble your Lemon Blueberry Domes. Start by spooning a layer of the lemon mousse into the silicone dome molds, filling them halfway. Next, add a piece of the blueberry jelly, followed by another mousse layer to fill the molds almost to the top. Finally, place the rounds of vanilla sponge on each dome and press gently. Freeze for at least 4 hours until completely firm.

For the glaze, reheat any leftover blueberry puree until warm, then add a touch of sugar if desired to enhance sweetness. Allow it to cool slightly before pouring it over the chilled domes. Remove the frozen lemon blueberry domes from the molds and place them on a wire rack. Drizzle the warm blueberry glaze over each dome, letting it cascade down the sides for an appealing presentation.

To serve your stunning Lemon Blueberry Domes, place them on a white platter for striking contrast. Garnish with freshly grated lemon zest and a handful of blueberries for a pop of color. These domes are not just desserts; they are a delightful centerpiece perfect for any gathering, showcasing the beautiful layers and flavors within.
