Rick, there is absolutely no cooking involved in Tiramisu. Unless you heat the eggs to 165 or so in a bain marie. The best cookies to use are Stella D'oro Margherite cookies, if you can't find ladyfingers. You can make single servings like I did or layer cookies and custard in an 8x8 dish. Then chill it a few hours and you're done.
I'm soon having my Italian snowbird friend from Brooklyn to dinner and will try this out on him.

Good coffee, good weed, and time on my hands...
