Food Network offers a recipe for Giada De Laurentiis' traditional tiramisu that calls for espresso, egg yolks, sugar, rum and ladyfingers. The recipe takes about 25 minutes to prepare and between two and eight hours to set in the refrigerator.
To make Giada De Laurentiis’ traditional tiramisu, prepare 1 1/2 cups of strong espresso, and allow it to cool. Whisk together 6 pasteurized egg yolks and 3 tablespoons of sugar with an electric mixer for approximately five minutes or until it is thick and lightly colored. Whisk in 1 pound of mascarpone until the mixture is smooth. Mix in 1 tablespoon of the cooled espresso.
In a separate dish, combine the remaining espresso with 2 teaspoons of dark rum. Dip 24 prepackaged ladyfingers into the liquid for about five seconds each. Avoid over-soaking the cookies, as this can cause them to break apart. Set a layer of ladyfingers at the bottom of a 13-by-9-inch baking pan, breaking them up as necessary to fit half of the ladyfingers into a single layer.
Spread half of the mascarpone mixture into a layer on top of the ladyfingers, and then top the mascarpone with another layer of ladyfingers. Spread the remaining mascarpone mixture on top of the second layer of ladyfingers.
Cover the dish with plastic wrap, and allow it to set in the refrigerator a minimum of two hours and up to eight hours. To serve, garnish the tiramisu with 1/2 cup of bittersweet chocolate shavings.
