I think this is one of the best cannoli that I have ever had! The original recipe calls for fat-free ricotta, but I used part skim. Also, the original recipe calls for 2 1/2 cups semisweet chocolate chips in the filling and 1/2 cups for melting. Instead, I used 2/3 cups mini semisweet chocolate chips in the filling, and I did not really think it was necessary to drizzle the chocolate on topr. Last, I think it is a good idea to chill the filling for at least an hour to let the flavors marry.
