Moca Semifreddo

Instructions

1. 1
   Line a standard rectangular loaf pan with plastic cling wrap, leaving plenty of overhang on the sides for easy removal later. Place the thin chocolate sponge or ladyfingers at the bottom of the pan.
2. 2
   In a heatproof bowl, whisk the egg yolks with 50 grams of sugar and the cold espresso. Set the bowl over a pot of gently simmering water (bain-marie, ensuring the bottom of the bowl doesn't touch the water) and whisk constantly for 5-6 minutes until thickened and pale. Remove from heat and let cool.
3. 3
   In a separate chilled bowl, whip the heavy cream and vanilla extract together until stiff peaks form. Place in the refrigerator.
4. 4
   In a third pristine bowl, whip the egg whites until foamy. Gradually add the remaining 50 grams of sugar while beating until you achieve a glossy, stiff-peaked meringue.
5. 5
   Gently assemble the dessert: fold the cooled coffee-egg mixture into the whipped cream using a rubber spatula in broad, circular motions.
6. 6
   Carefully fold in the meringue in two separate batches, working delicately from the bottom up to keep the mixture as airy and light as a cloud.
7. 7
   Pour the smooth cream into the prepared loaf pan over the cake base. Smooth the top with your spatula, fold the overhanging cling wrap over it, and freeze for at least 6 hours (preferably overnight).
8. 8
   Right before serving, whip the extra 100ml of cream and load it into a piping bag with a star tip. Unmold the semifreddo onto a serving platter and peel away the plastic wrap.
9. 9
   Pipe beautiful wavy patterns across the top surface and dust generously with unsweetened cocoa powder through a fine sieve, mirroring the look in Semifreddo.png. Slice with a warm knife and enjoy immediately.
