I know what frin's talking about, the things the guy at the corner shop used to use to pad out a ten-cent bag of mixed lollies. And they always had that kind of awkard perfumey smell about them, like presents for rarely-seen aunts at Christmas.
Lolly bananas, as I call them, are usually about 5cm long, banana shaped (of course), and an opaque light yellow. They sometimes have a slightly powdery surface as if they've been lightly dusted with cornflour. They are what I'd call a fondant candy, with a texture that ranges from slightly chewy to crisp and crunchy, depending on the degree of freshness. (Some fans insist on them being fresh, others will eat only stale ones.) The flavour has nothing with bananas to do, but comes from an ester that every chemistry teacher gets you to make in high school (isopentyl acetate maybe?).
I rather like them, but do feel quite sick if allowed to consume a whole bag of the things.
I looked and looked when I was living in the States and never once found them, although I did once try something that was orange coloured and not banana shaped but which otherwise had the exact same texture and flavour. Can't remember what they were called.
