Tell me I'm not crazy but does anyone else in Scotland, England, Ireland or Wales remember a Choc Ice called something like 'Midnight Mint' from the 1970's? Funnily enough it was mint flavoured, possibly with a plain chocolate coating and it came in a dark wrapper with an owl on the front.
No you are not crazy. I worked at Walls before 1970 and we made Midnight Mint Choc Ices exactly as you describe. One of my favourite ices. I wish that they would revive it. Fond memories from Charlieboy.
