Tiramisu

Pour egg yolks and sugar in an electric mixer and whisk together on high speed for 5 minutes until the mixture is light yellow and fluffy. Lower speed to medium and add 1/4 cup of dark rum, mascarpone cheese and orange zest and mix until smooth (1 minute).

Spoon and spread about 1/4 cup of the mascarpone mixture on a serving plate. I used a long and narrow plate in order to have only 1 row.

Pour the cooled espresso in a bowl add remaining 1/4 cup of dark rum. Quickly dip the savoiardi in coffee on 1 side only and arrange in a single layer side by side, wet side down over the mascarpone.

Once you have one layer of savoiardi down on the plate top with a thick layer of mascarpone mixture and then sprinkle with cocoa powder. Repeat this step twice and top you tiramisu with the shaved or grated bittersweet chocolate.

Refrigerate overnight.
