Lorenza's fool proof, works every time, Torta di Ciccolato

I know there is probably a plethora of different recipes out there for Chocolate Torte, but this is my trusty, fool proof, works every time, thank you Lorenza, recipe. And it goes without saying that if you use inferior chocolate your end result will be ordinary. But if you want to make an exquisite Torta di Ciccolato fit for a king, then use a chocolate with no less than a 75% level of cocoa.
