Angel delight is still available and still as synthetically gloopy as ever. Likewise Dream Tipping - remembr that? I used to be given something my mother called "pink pudding", which was a blancmange powder whisked up with milk. Haven't seen it around, probably because that's not its real name. It came in boxes of 5 sachets.
Wispa bars are still around (I remember them being the new bar on the block - sometime around the early 80s) and have spawned several derivative versions.
Creamola foam?
