Ingredients
- 4 whole large eggs, separated
- 100 g granulated sugar
- 200 g dark chocolate, chopped (70% cacao or higher)
- 60 g unsalted butter
- 120 ml whole milk
- 300 ml heavy cream, cold
- 1 tsp vanilla extract
- ¼ tsp fine sea salt
- 1 tbsp unsweetened cocoa powder for dusting
Instructions
- 1
Line a 9-by-5-inch loaf pan with plastic wrap, letting the edges overhang on all sides — this makes unmolding much easier. Place the lined pan in the freezer while you prepare the semifreddo base.
- 2
Fill a medium saucepan one-third full with water and bring to a gentle simmer over medium heat. You'll use this as a water bath to warm the egg yolks safely.
- 3
Separate 4 large eggs into two bowls — yolks in one bowl, whites in another, making sure no yolk enters the whites (even a trace of yolk will prevent proper whipping). Set the bowl with whites aside to come to room temperature.
- 4
To the bowl with the yolks, add 50 grams of the granulated sugar and a pinch of fine sea salt. Place the bowl over the simmering water bath (the bowl should not touch the water). Whisk constantly for 6–8 minutes, until the mixture reaches 160°F on an instant-read thermometer and feels warm — this pasteurizes the eggs and dissolves the sugar. Remove from heat.
- 5
Chop 200 grams of dark chocolate (70% cacao or higher) into pea-sized pieces and add to the warm egg yolk mixture along with 60 grams of unsalted butter. Let sit undisturbed for 1 minute, then whisk gently until the chocolate and butter melt completely into a smooth, glossy base.
- 6
Pour 120 ml of whole milk slowly into the chocolate mixture while whisking constantly to combine — this cools the mixture slightly and creates a silky custard. Stir in 1 teaspoon of vanilla extract. Set aside to cool for 5 minutes, stirring occasionally.
- 7
Using an electric mixer fitted with the whisk attachment on medium-high speed, beat the 4 room-temperature egg whites until soft peaks form — about 2 minutes — then gradually add the remaining 50 grams of granulated sugar while continuing to beat. Keep whipping for another 2–3 minutes until stiff, glossy peaks form and the mixture looks like meringue. This is crucial for the airy texture.
- 8
In a separate bowl, pour 300 ml of cold heavy cream and beat with the mixer on medium-high speed until stiff peaks form, about 2 minutes. The cream should hold its shape but still look silky — do not overbeat or it will turn to butter.
- 9
Pour the cooled chocolate custard into a large mixing bowl. Fold in the whipped egg whites in two additions using a silicone spatula, using large, gentle strokes from the bottom of the bowl up and over the top. Fold until no white streaks remain but the mixture still looks airy.
- 10
Gently fold the whipped cream into the chocolate-egg mixture in two additions, using the same folding technique. Work carefully — overworking will deflate the mousse and lose the light, frozen texture. Stop as soon as no white cream streaks remain.
- 11
Pour the chocolate mousse into the cold lined loaf pan, smoothing the top with a spatula. Fold the plastic wrap overhang back over the top to cover, then transfer to the freezer. Freeze for at least 6 hours, preferably overnight, until firm throughout.
- 12
To unmold, pull back the plastic wrap and briefly run a thin knife around the edges of the pan to loosen — do not force it. Place a serving plate on top, invert, and lift away the pan. Carefully peel off the plastic wrap.
- 13
Let the semifreddo sit at room temperature for 3–5 minutes before slicing — this allows it to soften slightly and become creamy. Using a warm, dry knife (wipe the blade between slices), cut into 1-inch-thick slices. Dust each slice lightly with unsweetened cocoa powder using a fine-mesh sieve, then serve immediately. The interior should be soft and mousse-like, not rock hard.
