Strawberry and Lychee Shaved Ice with Tropical Fruit Ceviche

Mexican raspados taste much better than the snow cones of my youth. Although they are both made with shaved ice, the Mexican version, like this combination of strawberries and lychees, is made only with fresh fruits and sugar, then frozen, and scraped before serving. I like to serve my version with a tropical fruit salad. Raspados can be made two days in advance and kept frozen in a covered container.
