The word ‘nangs‘ is Australian slang that refers to cream chargers which are cylinders containing nitrous oxide (N2O) gas.
Nangs or cream chargers are primarily used for whipped cream but are also designed for use in other food and drink preparations such as a foaming agent in sauces and mousses or a flavor infusing agent for alcohol for cocktails and other fancy alcoholic drinks.
