Tiramisu Classic Mascarpone

Brew strong espresso and let it cool completely. If you are using Marsala wine, stir it into the chilled espresso for an extra layer of flavor.

In a large bowl, whisk the egg yolks with half of the granulated sugar until the mixture becomes pale and creamy. Gently fold in the chilled mascarpone cheese until it is just combined and smooth, taking care not to overmix.

In a separate, very clean bowl, beat the egg whites using an electric mixer until soft peaks begin to form. Gradually add the remaining granulated sugar and continue beating until stiff, glossy peaks form.

Carefully fold the whipped egg whites into the mascarpone mixture in two additions. Be gentle to maintain the airiness and light texture of the cream.

Quickly dip each ladyfinger into the cooled espresso mixture, ensuring it is soaked but not soggy. Arrange a single layer of the soaked ladyfingers at the bottom of a 9x13 inch (23x33 cm) serving dish. Spread half of the mascarpone cream evenly over the ladyfingers. Repeat with another layer of espresso-soaked ladyfingers and the remaining mascarpone cream.

Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the flavors to meld and the dessert to set firmly. Just before serving, generously dust the top with unsweetened cocoa powder.
