The first question I have to ask myself when I eat this treat is "What is an Aero?" As far as I know an "Aero" bar is a bar full of bubbles that not only makes it lighter (why people want lighter bars I'm not sure) but also helps it melt in your mouth. This bar, although a tasty little treat, really didn't seem to fulfill its namesake. It did have a small thin layer of bubbly chocolate, but the layer was so thin that it really wasn't an "Aero". In my Aero bar review I commented that one third of the bar felt like it was air, that’s just not the case with the caramel version.
As far as being a good treat, it was fine. The chocolate is nice, the caramel smooth, but it just wasn't an "Aero" anymore. It seems like a standard chocolate caramel bar that you find all over the place. The trademark Aero bubbles just didn't hold up. When someone tells me I'm eating an "Aero" and then delivers another treat entirely, it makes me think that whomever came up with this treat is thinking more about banking on the name than the idea behind the treat. The Aero name is not needed, this treat holds up fine on its own, the small amount of bubbles is just not necessary and frankly doesn’t add anything to this bar.
This is an obvious problem of ratio, you need to have enough caramel to make it special, but you also need enough bubbles to keep it an Aero bar. If there was some way you could ad bubbles to caramel it would solve the whole problem.
