Shaved ice is a large family of ice-based desserts made of fine shavings of ice and sweet condiments or syrups. Usually, the syrup is added after the ice has been frozen and shaved—typically at the point of sale; however, flavoring can also be added before freezing. The dessert is consumed worldwide in various forms and ways. Shaved ice can also be mixed with large quantities of liquid to produce shaved ice drinks.
