Instructions:
1. Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease an 8-inch (20 cm) springform pan and line the bottom with parchment paper.
2. Prepare the Hazelnuts:
Spread the hazelnuts on a baking sheet and toast them in the preheated oven for about 10 minutes, or until they become fragrant. Once toasted, let them cool slightly, then rub them in a clean kitchen towel to remove most of the skins. Grind the hazelnuts in a food processor until finely ground (but do not let them turn into paste).
3. Melt the Chocolate and Butter:
In a heatproof bowl set over a saucepan of simmering water (double boiler), melt the dark chocolate and butter together, stirring occasionally until smooth. Once melted, remove the bowl from the heat and let it cool slightly.
4. Separate the Eggs:
Separate the egg yolks from the whites. Place the egg whites in a large, clean mixing bowl and the yolks in a separate bowl.
5. Mix the Yolks and Sugar:
Add the sugar to the bowl with the egg yolks and whisk until the mixture is pale and thick. This can be done using a hand mixer or a stand mixer on medium speed for about 3-5 minutes.
6. Combine Ingredients:
Gradually add the melted chocolate and butter mixture to the egg yolk mixture, stirring continuously until well combined. Then, gently fold in the ground hazelnuts and light sour cream until evenly incorporated.
7. Beat the Egg Whites:
Using a clean whisk or mixer, beat the egg whites until they form stiff peaks. Be careful not to overbeat, as this can cause them to become dry.
8. Fold in the Egg Whites:
Gently fold the beaten egg whites into the chocolate mixture in three additions, being careful to maintain as much air as possible in the batter.
9. Bake the Cake:
Pour the batter into the prepared springform pan and smooth the top with a spatula. Bake in the preheated oven for about 35-40 minutes, or until a toothpick inserted into the center of the cake comes out with a few moist crumbs (the center should be set but still moist).
10. Cool and Serve:
Let the cake cool in the pan on a wire rack for about 10-15 minutes, then run a knife around the edge of the pan to loosen the cake and remove the sides of the springform pan. Allow the cake to cool completely before serving.
11. Optional Garnish:
Dust the top of the cake with powdered sugar or cocoa powder. You can also serve with a dollop of whipped cream or a scoop of vanilla ice cream if desired.
Tips:
- Use good quality dark chocolate for the best flavor. A chocolate with around 70% cocoa will provide a rich, deep taste.
- Toasting the hazelnuts before grinding them adds an extra layer of flavor. Simply spread them on a baking sheet and toast at 350°F (175°C) for 10 minutes, then rub off the skins with a clean towel.
- Make sure your eggs are at room temperature before beginning. This allows them to mix better, giving you a smoother batter.
- When folding the beaten egg whites into the chocolate mixture, do it gently to maintain the airiness and ensure a light texture.
- Let the cake cool completely in the pan before removing it to avoid breakage. Using a springform pan can help with an easier release.
- Serve the cake with a dollop of light sour cream or a dusting of powdered sugar for an extra touch of elegance.
