Don't use American coffee in place of espresso. If you do use coffee, don't call the result Tiramisù, because it is not, and don't tell anybody where you got the recipe. Don't use 'espresso blend' coffee of any type. It is not Italian espresso. Use an Italian brand such as Cello, Lavazza, Kimbo, Mauro, Illy, etc. You should be able to find it at an Italian market. It will be packaged in a 250gr. foil brick. You don't have to use the most expensive brand, but make sure it is Italian. Starbucks doesn't make any coffee that is even remotely close to Italian espresso. Don't bother trying to use it. This recipe uses raw eggs.I use a electric mixer. Tiramisù can be made without a mixer. Many Italian families don't have power mixers. They are be able to make good Tiramisù. I'm not sure that I could though.
So, first off bring all the ingredients to room temperature.
Then mix/beat the egg yolks with the sugar until creamy white. Add marscapone and combine.
Then in another bowl beat the egg whites until fluffy.
Fold beaten egg whites into mascarpone mixture. Mix only enough to blend.
Now for the espresso. 'If at this point you've decided to use coffee instead of espresso, take the coffee you've made and drink it. Then make espresso.'
Pour the espresso (that should be room temperature) into a shallow flat-bottomed dish. Quickly dip the savoiardi biscuits into the espresso, remove and then lay then down one by one in the bottom of your serving dish, until the whole bottom of the dish is cover in one 'espresso-ed' savoiardi layer.
The online recipe notes: To get the right amount of espresso on the savoiardi, lay the finger flat in the bottom of the bowl sugared side UP and immediately pull it out. Place each finger flat in the bottom of the pan sugar side DOWN. The savoiardi will quickly absorb the espresso. If you soak the savoiardi in the espresso you will end up with soggy savoiardi instead of moist savoiardi.
Then spoon a layer (about 1cm thick) of the marscapone and egg mixture over the savoiardi base and dust with cocoa powder.
Now all you must do is repeat the process again, another layer of 'espresso-ed' savoiardi, another of the marscapone and egg mixture and then another dusting of cocoa powder and hey-presto your done! The woman on the youtube video noted to lie the second layer of savoiardi the opposite was to the first.
Try to refrigerate the tiramisu for 4 hours before serving, mine only got 2.5 hours in the fridge unfortunately but was still great. I recommend you watch the youtube clip once through, although all in Italian, just to see how she dips the savoiardi etc. Happy making. x
