I'm indebted to Neil for reminding me of the drink that was the mainstay of my childhood. Creamola Foam must have been a cheap alternative to the red cola and fizzy orange that appeared at parties and on holiday visits to cafés, but my main memory of drinking it is very clear - so clear that I can taste it now - and strongly linked to one place. That place is on Arran, at a point in North Glen Sannox (not to be confused with Glen Sannox, but a less-well-known glen slightly to the north) where huge slabs of pale grey granite jut out into the very middle of the North Sannox burn. This is still one of my favourite places on earth, and will forever be associated with what would be a typical 1950s picnic: Macvitas, triangles of Dairylea cheese, floury muffins with strawberry jam, slightly flattened from their sojurn in a rucksack - and Creamola Foam, preferably orange flavour, made in a plastic tumbler with water scooped precariously from the burn.
This was Creamola Foam at its best, and it's easy to see why it was a winner for whoever was carrying the drinks: a small tin and a spoon make for much less of a load than a bottle of diluted squash. Perhaps the location explains why I recall it with such fondness, for I am now convinced that in my childhood we never drank anything like enough water and at the end of a muddy walk we'd be parched with a thirst that made this chemical concoction into nectar.
To the best of my recollection, we never bought this stuff for my own kids - though I'm open to correction if they ever read this - because I have a feeling I tasted it in later life and realised my tastes had moved on. Just as well, really - it doesn't seem to exist these days.
Update: Neil assures me I did indeed buy it for him - he wouldn't have mentioned it otherwise.
