Make the Sponge Cake

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a round cake pan (about 8 inches) with parchment paper and lightly grease it.
2. Prepare the Cake Batter: In a mixing bowl, whisk the eggs with the sugar until light and fluffy, about 5-7 minutes. Stir in the honey and vanilla extract until well combined.
3. Sift the Dry Ingredients: Sift the flour into the egg mixture, folding it in gently using a spatula until just combined. Be careful not to deflate the batter.
4. Bake: Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 10-15 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean.
5. Cool: Let the sponge cake cool in the pan for 5 minutes before transferring it to a wire rack to cool completely.

Prepare the Raspberry Compote

1. Cook the Raspberries: In a small saucepan, combine the raspberries, sugar, and lemon juice. Cook over medium heat for about 5 minutes, stirring occasionally until the raspberries break down and the mixture thickens slightly.
2. Cool: Remove from heat and let it cool to room temperature before using it in the entremet.

Make the Honey Mousse

1. Bloom the Gelatin: If you’re using gelatin for added structure, bloom it in 2 tablespoons of water for about 5 minutes. Set aside.
2. Heat Honey: In a saucepan, heat the honey and water over low heat until it begins to simmer. Stir in the bloomed gelatin (if using) until dissolved completely.
3. Whip the Cream: In a separate bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the honey mixture, then add the vanilla extract.
4. Chill: Allow the mousse to chill in the refrigerator for 30-45 minutes to firm up slightly before assembling the entremet.

Assemble the Entremet

1. Prepare the Cake Base: Slice the cooled sponge cake into two or three even layers, depending on how many layers you prefer in your entremet.
2. Layer the Mousse and Compote: In a ring mold or a high-sided cake pan, layer the sponge cake at the bottom. Spread a generous layer of raspberry compote on top, followed by a thick layer of honey mousse. Repeat the layers as desired.
3. Chill: Once the entremet is fully assembled, refrigerate it for at least 4-5 hours, or preferably overnight, to allow the mousse to set properly.

Finishing Touches

1. Decorate: Once the entremet is set, carefully remove it from the mold. Drizzle raspberry purée on top, then garnish with fresh raspberries and a few edible flowers or mint leaves for a fresh, vibrant touch.
