It is possible to find the lady fingers and mascarpone cheese in supermarkets or other locations in a large city?
I haven't looked yet.
Edit - OK I see below that Costco sells them- perhaps I'll spend my efforts on something else. My wife often buys their cheescake for parties but I find it too rich and not that refined but I suppose this may be a good thing with Tiramisu.
I was also planning on making a hazelnut-chocolate cake from Americas test Kitchen Italian recipe book. They also list a almond cake which sounds very refined.
