Forget your carnival midway snow cones and Stop-and-Rob Slurpees. And Hawaiian shave ice (only mainland haolesdare to call it shaved ice) isn't even in the running. All hail the new king of frozen desserts -- the raspado, Mexico's luscious take on fruit-flavored syrup drizzled over finely crushed ice. What separates the divine raspado from its other, more pedestrian brain-freeze bros is its liberal dousing of plain shaved ice with both thick syrup and small chunks of fresh ripe fruit in season, like mango, plum, peach, strawberry and melon. Add to your list of choices banana, vanilla, walnut, orange, coconut, tamarind, lime and piña colada, and just about every other season is adequately represented. We seriously doubt that the creator of the Mexican raspado was aware of its real history, which dates back to A.D. 62. That's when ultimate party animal and Roman emperor Nero got the bright idea of ordering his slaves to the nearby Apennines to schlep back snow and ice to Rome, where it was pummeled into slush and doused with honey and fruit pulp. Chances are Nero's original version wouldn't even come close to the latter-day Phoenix version being dished up at Oasis Raspados.
