La Beccharie's Original Tiramisu

If you haven't noticed by now, I currently have a thing for Tiramisu...

The next recipe I will test on my road to the most delicious, fresh and simple Tiramisu is what Anna Maria Volpi claims to be the original recipe from La Beccherie.

It has the simplicity of ingredients I am looking for (no gelatine, condensed milk, etc); it is only *slightly* more complicated than my current recipe, through the addition of whipped cream. I might have a problem with finding 1.5c of espresso, though - I don't have an espresso maker, and I've never ordered it before. I have a feeling that even if I use the Mascarpone Cream of this recipe, I'll go back to my current method of 1 part strong coffee, 1 part kahlua. So that begs the question - what's different in this cream? Less Zabaglione, more Cheese/Cream. We shall see...
