There were days when fine foamy drink required a team of dedicated shakers to achieve an fluffy and long lasting consistency.
Fast forward to the advent of molecular gastronmy and the closing of proximity between bar and kitchen, quickly nitrous creamers came to the fore, charging emulsions that could be floated across the surface of a drink, quite literally adding a new layer of enjoyment to your tasty beverage.
