1. Super-cool ice cream
Steamy-cold liquid nitrogen is becoming an increasingly popular way to fast-freeze made-to-order ice cream. In Houston, Sub Zero Nitrogen Ice Cream & Yogurt added a new location to its growing brand, which markets itself through catering and school presentations on the science behind liquid nitrogen ice cream. And in Spring Valley, Nev., near Las Vegas, soon-to-open Sweetspot Nitrogen Ice Cream & Boba Tea menus a creative flavor list that includes pomegranate, Lucky Charms, birthday cake and more. Toppings have an Asian focus, with choices like mango popping boba, matcha green Kit Kat and rainbow mochi.
