Laughing gas chocolate bubbles with joy
Chocolate made with laughing gas is more enjoyable, according to a study published in Chemistry & Industry magazine.
Also known as nitrous oxide, laughing gas apparently produces a more intense flavour when used to put bubbles in chocolate.
Researchers at the University of Reading tested a chocolate selection made with four different gases – nitrous oxide, nitrogen, argon and carbon dioxide. Nestle, the maker of Aero, provided a recipe for the chocolate, which was assessed by a panel of 20 non-expert testers.
The testers agreed the chocolate made with laughing gas had the most intense cocoa flavour and melted rapidly in the mouth, while the chocolate made with argon or nitrogen produced smaller bubbles and was believed to be harder and creamier because the chocolate took longer to melt.
