It sounds like something you’d encounter on a cruise ship, but Paolo Dalla Zorza of Paolo’s Gelato says the idea for his new cannoli service came to him while traveling home from Italy. Now at Paolo’s, customers have their pick of cannoli shells, fillings and toppings, so they can construct a mini-shell stuffed with chocolate ricotta cream and dipped in candied fruit, or a chocolate-coated shell filled with ricotta and garnished with sprinkles. There are 72 possible different combinations. “My customers are so international and well-traveled, so they appreciate this kind of an idea,” Zorza is quoted as saying in a release. Paolo’s is located at 41 John St.
