The key to classic Italian Tiramisu is the texture: be sure to whip the egg whites until light and fluffy, fold them in gently, and only dip the cookies for a brief moment so they keep their shape.
1 to 2tablespoonsdark rumamaretto, or brandy (optional)
24(200g) store-bought ladyfinger cookies
Cocoa powder,for dusting
Instructions
Beat the egg whites to stiff peaks. Separate the egg whites and egg yolks into two large mixing bowls. Use a hand mixer in medium-high speed to whip the egg whites until stiff peaks form (when you pull up on the mixer the eggs hold their shape), about 4 minutes. Set aside.
Whip the egg yolks and sugar. Add the sugar to the bowl with the egg yolks. Whip on medium-high speed until tripled in volume and pale yellow, about 4 minutes.
Combine. To the yolk mixture, add the mascarpone and beat on medium-low speed until smooth. Add the egg whites and gently fold with a rubber spatula until just combined, being careful not to deflate the air.
Assemble the tiramisu: Add the coffee to a wide shallow bowl. Optionally, stir in the liquor. Working one cookie at a time, dip half of the ladyfingers into the coffee, about 1/2-second per side, and arrange in a single layer in an 11x7-inch or 9x9-inch pan. Spread half of the mascarpone mixture over the ladyfingers.
Layer. Dip the remaining ladyfingers in the coffee and arrange over the mascarpone cream. Spread the remaining mascarpone cream over the top.
Chill: Cover the pan and refrigerate for at least 6 hours, preferably overnight.
Serve: Dust the top of the tiramisu generously with cocoa powder, slice, and serve.
Storage: Cover and store in the refrigerator for 2 to 3 days.
Best coffee to use: Most tiramisu recipes call for espresso, but most of us don’t have an espresso machine at home. While you could ask your nearest coffee shop to make 1/2 cup worth of espresso shots for you, I just brew an extra strong batch at home with my regular coffee maker or use a good quality espresso powder. Most households in Italy have a moka pot and the rich, espresso-like coffee it makes works perfectly in tiramisu. If you have a pod machine, you can use as many espresso pods as it takes to brew 1/2 cup. When I use espresso powder, I dissolve 2 tablespoons into 1/2 cup of hot water.
