Used to be popular at children's parties, no reason why it shouldn't still be.
Easy to make. A pint of milk a spoonful of sugar, mix, heat up to boiling, simmer for 5 minutes, leave to cool, into the fridge for 3 hours and then enjoy.
amazing, couldn't find it in any shop locally as I specifically wanted the raspberry flavour, then I tried Ebay, not really thinking I would find it, and bingo .... there it was. really happy with my purchase
