Orange Chocolate Semifreddo

Instructions

1. 1

   In a double boiler, melt the dark chocolate, stirring occasionally, until smooth.

   Tip: Be patient, as this step can take several minutes.

2. 2

   In a separate bowl, whisk together the egg yolks, granulated sugar, orange juice, orange zest, and orange extract (if using) until pale and thickened.

   Tip: Make sure to whisk until the mixture is pale and thickened, as this will help prevent scrambling the eggs.

3. 3

   In a separate saucepan, whisk together the heavy cream, unsalted butter, and confectioners' sugar until stiff peaks form.

   Tip: This step should take about 5 minutes, and is crucial for the whipped cream's texture.

4. 4

   To assemble the semifreddo, pour the chocolate mixture into a 20cm x 5cm x 5cm loaf pan, followed by the whipped cream mixture, and finally the orange marmalade (if using).

   Tip: Make sure to spread the whipped cream evenly to avoid any lumps.

5. 5

   Freeze the semifreddo for at least 2 hours, or until firm to the touch.

   Tip: It's essential to freeze the semifreddo until firm, as this will help it set properly and make it easier to unmold.

6. 6

   To unmold the semifreddo, run the pan under warm water for a few seconds, then invert onto a serving plate.

   Tip: This will help the semifreddo release from the pan without breaking.

7. 7

   Dust the semifreddo with confectioners' sugar and serve immediately.

   Tip: The confectioners' sugar will help to balance the sweetness of the dessert and add a nice textural element.

8. 8

   Slice the semifreddo into individual portions and serve.

   Tip: This will make it easier to serve and portion out the dessert to your guests.
