About a year ago I made Limoncello from this recipe:
http://biology.clc.uc.edu/fankhauser/Cheese/Limoncello.htmIt turned out excellent. After I bottled it I gave some away as gifts and used what I had leftover (besides drinking) for flavoring dishes, for example: crab cakes, shrimp scampi, grilled chicken, bitter chocolate & lemon cakes/souffles, &c.
Dr. Frankhauser, from the website above, is a Professor of Biology and Chemistry from Ohio. I have also used his (highly useful) step by step instructions for making cheese and "Pane Rustica," a European peasant bread, with great results!
