Tiramisu Alla Milanese

For 4 persons. Place mascarpone, the yellow of the eggs and sugar in a bowl and then whip until it gets homogeneous and thick (you could use an electrical whipper). Dip quickly one by one the savoiardi cookies in freshly prepared hot coffee (mixed with marsala in the alcoholic version) and place them in another glass bowl (better a flat one) in one or more layers depending upon the size of the bowl. Pour the mascarpone sauce on such layers and cover the whole sauce with chocolate dust (make it as fine as you can). Place at 4 !C for at least two hours and serve after an italian dinner.
