Tiramisu II

6 egg yolks

¾ cup white sugar

⅔ cup milk

1 ¼ cups heavy cream

½ teaspoon vanilla extract

1 pound mascarpone cheese, at room temperature

¼ cup strong brewed coffee, at room temperature

2 tablespoons rum

2 (3 ounce) packages ladyfinger cookies

1 tablespoon unsweetened cocoa powder

In a medium saucepan, whisk together egg yolks and sugar until well blended. Whisk in milk and cook over medium heat, stirring constantly, until mixture boils. Boil gently for 1 minute, remove from heat and allow to cool slightly. Cover tightly and chill in refrigerator 1 hour.

In a medium bowl, beat cream with vanilla until stiff peaks form.

Whisk mascarpone into yolk mixture until smooth.

In a small bowl, combine coffee and rum. Split ladyfingers in half lengthwise and drizzle with coffee mixture.

Arrange half of soaked ladyfingers in bottom of a 7x11 inch dish. Spread half of mascarpone mixture over ladyfingers, then half of whipped cream over that. Repeat layers and sprinkle with cocoa. Cover and refrigerate 4 to 6 hours, until set.
