Tiramisu Americas Test Kitchen Recipes

Steps:

• For the mascarpone custard: Add the egg yolks, sugar and Marsala to a medium heatproof bowl and whisk to combine. Set the bowl over a medium saucepan of gently simmering water (do not allow the bowl to touch the water). Whisk constantly until the mixture is pale, hot to the touch and has doubled in volume, 4 to 6 minutes, scraping down the sides of the bowl occasionally with a rubber spatula. (This can be done with an electric mixer to speed up the process.) Remove from the heat and continue whisking until slightly cooled, about 1 minute. Whisk in the mascarpone cheese until combined. Refrigerate until ready to assemble.
• To assemble: Stir together 1 1/4 cups hot water, espresso powder and 3 to 4 tablespoons Marsala in a liquid measuring cup. Evenly divide the mixture between two medium bowls. Dust the bottom of an 8-by-8-inch baking dish with 1 teaspoon cocoa powder.
• Working one at a time, dip half of the ladyfingers into one bowl of the espresso mixture for 2 seconds per side, until soaked but not soggy. Arrange them over the cocoa powder in one layer, breaking up as needed to fill in any gaps. Pour any remaining liquid from the first bowl over the layer of ladyfingers. Spread half the mascarpone custard over the ladyfingers. Repeat the process with another layer of ladyfingers and the remaining bowl of espresso mixture, then spread with the remaining mascarpone custard.
• Cover with plastic wrap and refrigerate for at least 4 hours or up to overnight. Sift the remaining 1 tablespoon cocoa powder over the top just before serving.

Steps:

• 1. Stir coffee, espresso, and 5 tablespoons rum in wide bowl or baking dish until espresso dissolves; set aside. 2. In bowl of standing mixer fitted with whisk attachment, beat yolks at low speed until just combined. Add sugar and salt and beat at medium-high speed until pale yellow, 1 1/2 to 2 minutes, scraping down bowl with rubber spatula once or twice. Add remaining 4 tablespoons rum and beat at medium speed until just combined, 20 to 30 seconds; scrape bowl. Add mascarpone and beat at medium speed until no lumps remain, 30 to 45 seconds, scraping down bowl once or twice. Transfer mixture to large bowl and set aside. 3. In now-empty mixer bowl (no need to clean bowl), beat cream at medium speed until frothy, 1 to 1 1/2 minutes. Increase speed to high and continue to beat until cream holds stiff peaks, 1 to 1 1/2 minutes longer. Using rubber spatula, fold one-third of whipped cream into mascarpone mixture to lighten, then gently fold in remaining whipped cream until no white streaks remain. Set mascarpone mixture aside. Cover with plastic wrap and refrigerate 6 to 24 hours. Sprinkle with grated chocolate, if using; cut into pieces and serve chilled.
