Ana and Lydia's cannoli, recipe invented on July 31st, 2005. I spent a lot of time looking for a good recipe for cannoli shells and filling. Since no two were alike, and since instructions were a bit sketchy, I worked with a friend to come up with a good recipe, including some tips that we came up with along the way. Special equipment is needed such as cannoli tubes, a pasta machine and a pastry bag to help make these cannoli come out just like the ones at Italian restaurants and bakeries. Start with 1/2 cup of confectioners' sugar, and then add more to taste.
