Be on the look out for Enticed, a gourmet shaved ice truck (not to be confused with smushed, grinded or jack hammered ice). Yesterday I talked to Lauren Noblett, the truck's shaved ice expert, and she divulged the secret to their delicious snow cones, which I promised not to share. (They rotate a large cylindrical piece of ice on skewers and delicately shave it off.)
According to my chemistry background (or a random website), shaved cylindrical ice absorbs more syrup than the standard block ice, meaning your piña colada juice doesn't collect at the bottom of the cup.
Finally, someone figured that out.
Enticed has a beaucoup of flavors, 35 in all and even nine sugar free, which they promise don't taste like punishment. They also make their own syrups and don't use high fructose corn syrup.
