Tiramisu

Step 1 

In a large heatproof bowl, combine egg yolks, ¼-cup sugar, and salt. Set the bowl over a saucepan of simmering water. Whisk the mixture until the sugar dissolves and the egg yolks turn to a light-pale yellow color. About 5-6 minutes. Remove from heat and set aside. Allow the mixture to cool. Stir occasionally.

Step 2

In a large bowl, beat the cream and the rest of the sugar (1/4 cup) until soft peaks form. Add vanilla and mascarpone cheese and continue beating at medium speed until medium peaks form.

Step 3

Fold the mascarpone mixture with the cool egg yolk mixture until combined and smooth.

Step 4

Mix espresso with rum. 

Step 5

Assemble the tiramisu. Dip ladyfingers, one at a time in the coffee mixture. Arrange in a single layer at the bottom of a 9x9 square pan. Spread half of the mascarpone cream on top. Dust half of the cocoa powder over it. Repeat process for a second layer of ladyfingers, cream and cocoa.

Step 6 

Refrigerate for at least 4 hours or overnight.
