This is our granizato.This example seems to use artificial colors

. The best do not. In New York, we call granizato it Italian ice. If the ice is very fine and whipped we call it sorbet. I agree with Bob, frozen fruit drinks ice and fruit in a blender, that you can drink with a straw are fruit smoothies, but different regions have different words for the same product. For instance, when I lived in the state of Delaware, smoothies made with lemon were called water ice popular on St Anthony's day in June.
Sherbet is like italian ice but with some milk in it.
