International candy is so wonderfully random and varied, you can’t help but love it. At the top of my list of fun international candies from my youth has to be Aero, made by Nestle. Aero is a UK creation, and was first made by the Rowntree Mackintosh company in 1935 (Nestle bought Rowntree Mackintosh in 1988). Above all else, Aero is a novelty bar, and not some extraordinarily fine bittersweet chocolate.
The novelty, in this case, is that Aero bars have a bubbly, aerated chocolate filling, which creates a pretty unique texture. Tellingly, the tagline of Aero is “have you felt the bubbles melt?”If you cut the bars open you can really see the bubbly interior – check it out below. Though we searched the web for how the bubbles in Aero form, it seems to be a closely guarded and much-speculated secret. Aero bars also come in dark chocolate and mint varieties – check out the awesome green color below! Aero is available at Cost Plus infrequently, and any respectable British Market.
