* You may need only about 2 1/2 boxes of ladyfingers, depending on the size of your dish, or the size of the cookies. To be on the safe side, get 3 boxes.
** Don't be afraid to use a generous dusting of unsweetened cocoa powder - the bitterness of the coffee and cocoa is completely balanced and mellowed out by the sweet ladyfingers and mascarpone cream. In every bite, you should distinctly taste the chocolate, and the coffee layers. If you don't, use more cocoa powder next time.
