Chocolate Vanilla Mousse

Ingredients

• 8 oz Bittersweet Chocolate (66‑72% cocoa, chopped into small pieces)
• 2 oz Unsalted Butter (Room temperature, cut into cubes)
• 2 tsp Vanilla Extract (Pure vanilla extract)
• 2 pinches Salt (Fine sea salt, divided)
• 4 Egg Yolks (Large eggs, room temperature)
• 1/2 cup Granulated Sugar (Divided: 1/4 cup for yolks, 1/4 cup for egg whites)
• 4 Egg Whites (Large eggs, room temperature)
• 1 cup Heavy Cream (Cold, for optional topping)
• 1 tsp Flaky Sea Salt (For garnish)

Instructions

1. Melt Chocolate and Butter

   Set a saucepan of simmering water on low heat. Place a heat‑proof bowl on top, making sure the bottom does not touch the water. Add the chopped chocolate and butter cubes. Stir every few minutes until fully melted and glossy.

   Time: PT10M

2. Add Vanilla and Salt, Cool Chocolate

   Remove the bowl from heat. Stir in 1 tsp vanilla extract and a pinch of salt. Let the mixture sit, stirring occasionally, until it reaches room temperature (about 15 minutes).

   Time: PT15M

3. Separate Eggs

   Separate 4 egg yolks from 4 egg whites, keeping each in its own bowl. Keep the yolks at room temperature.

   Time: PT5M

4. Whisk Yolks with Sugar Over Heat

   Place the yolk bowl over the same double boiler (or a second bowl over simmering water). Add 1/4 cup granulated sugar. Whisk continuously until the mixture becomes pale, thick, and the sugar has dissolved, about 5 minutes.

   Time: PT5M

5. Flavor Yolks

   Stir in the remaining 1 tsp vanilla extract and a pinch of salt until fully incorporated.

   Time: PT2M

6. Whisk Egg Whites Until Frothy

   Using a clean bowl and clean beaters, whisk the 4 egg whites with a pinch of salt until they become frothy and slightly foamy.

   Time: PT2M

7. Add Sugar and Whisk to Soft Peaks

   With the mixer on medium speed, slowly drizzle the remaining 1/4 cup sugar into the egg whites while continuing to whisk. Increase speed and whisk until glossy soft peaks form (the peaks should gently fold over).

   Time: PT8M

8. Combine Chocolate and Yolks

   Add the cooled chocolate‑butter mixture to the yolk‑sugar mixture. Using a large rubber spatula, fold gently until just combined; the mixture will look slightly glossy.

   Time: PT3M

9. Fold in Egg Whites

   Add about one‑third of the whipped egg whites to the chocolate‑yolk base. Fold gently to incorporate, then repeat with the remaining whites in two more additions, folding until no white streaks remain but the mixture is still light.

   Time: PT5M

10. Portion and Chill

    Spoon the mousse into individual ramekins or a large serving bowl. Cover tightly with plastic wrap and refrigerate for at least 12 hours (overnight) until fully set.

    Time: PT5M

11. Optional Whipped Cream Topping

    Just before serving, whip the heavy cream with a pinch of vanilla until soft peaks form. Dollop onto each mousse serving and sprinkle lightly with flaky sea salt.

    Time: PT5M
