Grattachecca

Grattachecca is a shaved ice originating in Rome, Italy. Commonly sold in kiosks and bars as street food, it consists of hand-shaved ice topped with various flavors of sweet syrup. In contemporary times, some grattachecca vendors use a mechanical ice crusher, rather than shaving or grating the ice by hand; some vendors believe that using a machine is more hygienic compared to hand shaving the ice.
