First prepare the coffee using a Moka machine big enough to serve 12 (about 3 cups) pour it in a bowl and allow to cool off, add 2 tablespoons sugar
or sweeten to taste.
Mix the egg yolks with 2 ounces sugar, and mix until you obtain a creamy light mixture. Work the mascarpone in a bowl using a wooden spoon, making sure you eliminate any lumps, then add the mascarpone to the sugar-egg mixture and continue to mix well.
In a separate bowl, mix the egg whites, pinch of salt, and the remaining 2 ounces sugar, until they reach a somewhat firm, but fluffy consistency, then add them to the mascarpone mixture. Stir in the rum
, if using.
Dip the savoiardi cookies (firm ladyfingers
) in the coffee
, and one by one lay them flat into a 7 by 11 pyrex tray, making sure you do not soak the cookies, as you want to make sure they maintain their firmness. Once the first layer of cookies has been laid out, spread a layer of the mascarpone cream
on top, and dust
with 1 tablespoon cocoa powder.
Now, again, prepare another layer of coffee-dipped cookies
, cream and cocoa powder
. Garnish the top of the cake
with the shaved dark chocolate
Cover the tray with plastic wrap
and refrigerate for about 3 hours so the flavors can marry and the tiramisu can settle.
