Decadent Tiramisu

A traditional Italian tiramisu made with a cooked custard base instead of raw eggs. The yolks and sugar get whisked over a double boiler until thick and pale yellow, essentially a hot zabaglione, which kills any salmonella concerns and gives the cream a silkier, more stable texture than the raw-egg version.

Mascarpone is the move that separates real tiramisu from cream-cheese imitations. Its high butterfat content gives the filling its signature creamy density and slight tang. There is no substitute. American cream cheese versions taste sour and dense in comparison.

The brandy-coffee soak is restrained here. Just three-quarters of a cup of liquid for two packages of ladyfingers, brushed on rather than dunked. Brushing prevents the soggy bottom that ruins so many tiramisus. The biscuits stay structurally intact while still picking up the bitter coffee and warm brandy notes.

The overnight chill is essential. Eight hours minimum lets the layers meld, the ladyfingers absorb moisture from the cream, and the dessert set up firmly enough to slice.

Pro Tips

• Whisk the yolk-sugar mixture constantly over the double boiler. Stopping causes scrambled eggs at the bottom of the bowl.
• Use full-fat mascarpone, never light or low-fat versions. The fat is what keeps the filling stable.
• Whip the cream to soft peaks, not stiff. Stiff peaks fold in poorly and leave white streaks.
• Brush the cut side of the ladyfingers, never the rounded outer side. The cut surface absorbs the soak more evenly.
• Don’t skip the 8-hour chill. Same-day tiramisu is loose and falls apart on the spoon.

Variations

• Substitute Marsala wine or dark rum for the brandy for a more traditional Italian profile.
• Use espresso instead of instant coffee granules for a bolder, more authentic flavor.
• Top with cocoa powder dusted heavily through a fine sieve instead of grated unsweetened chocolate.
