'wooly's ice' on Serious Eats
Cold icy desserts are probably the most refreshing snack you can get out of a street cart. Wooly's Ice's Green Tea Ice recipe in Alexandra Penfold and Siobhan Wallace's new cookbook, New York a la Cart, is a perfect example. While the guys behind the cart make their ices with a heavy-duty ice shaver, it is easy to replicate the process by freezing green tea and condensed milk granita-style. Simply pour your base into a large baking dish, and stir with a fork every 30 minutes or so until every bit has frozen into fluffy bits.
