Freddo Frogs and Caramello Koalas -- classic Australian kid bait (or as I see Cadbury refers to them, 'pre-teens confectionary').
They need to be consumed fridge cold in my opinion. They aren't proper chocolate of course (being about 30% sugar and only 23% cocoa solids), so chilling them doesn't cause any more distress to food snobs than simply eating them in the first place. I am pleased to see though that when Cadbury switched a proportion of the product's cocoa butter to palm oil, sales suffered and they switched back in 2009.
When Sarah Turnbull, author of Almost French, married a Frenchman called Frédéric, he was (perhaps inevitably) quickly dubbed Freddo by her Australian family.
