Nancy, this isn't authentic, but I've had this on my "to try" list for a while.
http://www.canadianliving.com/food/cannoli_tartlets.phpI made a cannoli filling a few years back that called for cooking the ricotta somewhat and adding a cornstarch slurry to thicken it up so wasn't sure how thick this recipe would be. But it's usually a good source for me.
I'm trying to avoid the whole frying the pastry part of the deal.
New York cannoli....yum.
