Fluffy Chocolate Mousse with Fresh Forest Berries

Lightly whisk the egg yolk in a small bowl. Break the dark chocolate into small pieces and set aside.

In a small saucepan, heat the milk with the sugar over medium heat to 38–40 °C. Take a ladleful of the warm milk, add it to the egg yolk, and immediately whisk until smooth. Bring the remaining milk-sugar mixture to a boil. Once it boils, add the egg yolk mixture, stirring constantly, and let it simmer briefly (approx. 5 seconds) over low heat. Remove from the heat.

Soak the gelatin leaves in a bowl of cold water for about 3 minutes. Drain the water, leaving about 100 ml. Melt the gelatin in the microwave at 700 W for about 1 minute. Stir the dissolved gelatin into the egg yolk mixture, add the chocolate pieces, and stir until the chocolate is completely melted. Transfer the mixture to a cold bowl and let it cool to about 35 °C.
